ISL68224

Dual-channel multiphase step-down controller (up to 8 phases: 6+2 or 5+3) with D-CAP+ control, PMBus telemetry and on-chip NVM. Covers 4.5-17 V in, 0.25-2.8125 V out at up to 300 A, switching 300 kHz-1 MHz in a 5x5 mm 40-pin WQFN. Undershoot-reduction and dynamic phase shedding cut output capacitance and hold efficiency across light and heavy loads, so AI-accelerator and FPGA core rails get tighter transient response with a smaller BOM; NVM stores the tuned configuration and trims external parts. Proven in TI reference designs for Xilinx Versal ACAP and Virtex UltraScale+ 200-A rails (PMP22165, TIDA-050020). Sourcing note: pair with TI NexFET smart power stages such as CSD95490 as in the official EVM; if a single rail must exceed about 300 A, step up to the 12-phase TPS536C7 instead of paralleling controllers. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS53688 is a Texas Instruments dual-channel D-CAP+ multiphase step-down controller scaling to 8 phases (N+M ≤ 8) with Intel VR13.HC SVID and PMBus — for AI-accelerator, FPGA and datacenter ASIC core rails demanding up to 765 A. 4.5 V to 17 V input, 0.25 V to 5.5 V output, 5x5 mm 40-pin WQFN, -40°C to +125°C. SVID gives the processor direct voltage control for dynamic frequency scaling, while PMBus telemetry reports voltage, current, power and temperature per rail — the visibility datacenter operators require for fleet power management. Selection advice: compared with the 8-phase TPS53681 (which adds on-chip NVM), choose TPS53688 when the platform requires Intel SVID compliance; for 12-phase/400 A rails step up to the TPS536C7 on this site. Pair with TI NexFET smart power stages per the TIDA-010241 FPGA reference design. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Dual-channel D-CAP+ multiphase controller scaling to 12 phases (12+0, 11+1 or 10+2) for up to 400 A on datacenter ASIC and AI-accelerator core rails. 4.5-18 V input, 0.25-5 V output, PMBus telemetry and fault reporting, 6x6 mm 48-pin VQFN. The 12-phase interleaving spreads current and heat, letting one controller replace paralleled regulators on 360-A-class rails - TI's PMP21887 reference design demonstrates 360 A continuous / 600 A peak for datacenter hardware. Sourcing note: compared with the 8-phase TPS53681 (which adds NVM), choose TPS536C7 when the rail exceeds about 300 A or needs 12-phase granularity; the datasheet orderable is listed as TPS536C7B1, so confirm the exact suffix on your PO. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

XDPE132G5H is an Infineon 16-phase digital PWM multiphase controller in 7x7mm 56-pin QFN — for next-generation AI server and 5G networking voltage regulators delivering 500A to 1000A+: true 16-phase digital engine with 0.625mV Vout steps, PMBus 1.3/AVSBus, AMD SVI2 and NVIDIA PWMVID support. True active current sharing eliminates doubler ICs, and the digitally programmable load line removes external components. Selection advice: this H variant is the active generation — the older XDPE132G5C is superseded; pair with the 70A TDA21475 power stage for 1000A+ designs per Infineon reference. For sub-500A rails a fewer-phase controller costs less — size the phase count to your peak current plus margin. Parameters verified against Infineon documentation.

A4988SETTR-T is an Allegro MicroSystems DMOS microstepping stepper motor driver in QFN-28, tape and reel — for 3D printers, CNC machines and consumer motion control where a proven low-cost stepper driver matters. Built-in translator with full-step down to 1/16 microstepping, 35 V and ±2 A drive is the selection point: one STEP pulse equals one microstep, no phase tables to program. Selection advice: the SETTR-T suffix denotes the QFN-28 package in tape and reel; the SET temperature grade covers −20 °C to +85 °C. Against the TI DRV8825 on this site (45 V, 2.5 A, 1/32 step): the A4988 costs less and is the 3D-printing classic, but tops out at 1/16 microstepping and lower voltage — pick it when the motor fits within 35 V and 2 A. Synchronous rectification keeps dissipation low; thermal shutdown and short-circuit protections are built in. On 3D-printer StepStick-style modules the A4988 and DRV8825 footprints are largely interchangeable — but check driver orientation, microstepping jumpers and current setting before swapping, as the two parts differ. Parameters verified against distributor and manufacturer documentation.

ADP151AUJZ-3.3-R7 is an Analog Devices ultralow-noise 3.3 V LDO regulator in TSOT-23-5, tape and reel — for noise-sensitive rails: RF, VCO and PLL supplies where output noise matters more than current. 9 microvolt RMS noise with no bypass capacitor required is the selection point: ultralow noise without the extra capacitor that competing LDOs need. Selection advice: the R7 suffix denotes tape and reel on a 7-inch reel; against the LD1086DT33TR on this site — the ADP151 is the 200 mA precision part, the LD1086 the 1.5 A workhorse. 2.2 V to 5.5 V input, 150 mV dropout at 200 mA, 70 dB PSRR at 10 kHz. −40 °C to +125 °C. ADI lists this part as Active through distribution. Parameters verified against distributor and manufacturer documentation.

AL58263A is a Diodes Incorporated 16-channel constant-current LED driver with 16-bit grayscale Adaptive Pulse Density Modulation (APDM) — for indoor/outdoor LED video displays, variable message signs, traffic signs, billboards and LCD backlighting where uniform brightness and flicker-free dimming decide display quality. The APDM architecture is the selection point: by mitigating non-ideal output-current distortion from non-symmetric transient responses and separating frame waveform components, it improves output-current linearity and raises the system refresh rate versus conventional PWM dimming. It runs from 3.0 V to 5.0 V, supports output channel voltages up to 15 V, interfaces with a 25 MHz data clock, and delivers up to 45 mA of precise programmable current per channel. Each channel current is set through the digital interface, while the overall range is set by one external sensing resistor plus two independent 4-bit global current-gain controls (separate Group A and Group B banks). Accuracy is 1.5% typical / 3.5% maximum channel-to-channel current skew and 3% typical / 6% maximum chip-to-chip skew, with 0.1%/V output-voltage regulation, and built-in LED open/short diagnostics whose results are stored in registers for MCU readout, plus a 155°C thermal alarm with 15°C hysteresis. It comes in a thermally enhanced TSSOP-24EP package with exposed pad, rated -40°C to +105°C ambient. Selection advice: do not treat the A variant as a drop-in identical to the base AL58263 — the base part runs 3.0 V to 5.5 V with up to 55 mA per channel and a single 6-bit global current control, so re-check voltage headroom, current budget and gain-register programming when swapping. Solder the exposed thermal pad and provide a generous copper spread for full-current operation. Featured on Mouser New Products (2026-10-15). Parameters verified against Diodes Incorporated documentation.

AMS1117-3.3 is a 3.3 V, 1 A low-dropout linear regulator in a SOT-223 package, for general-purpose power rails in embedded and consumer designs. Its advantage is simplicity: a fixed 3.3 V output with minimal external components, which keeps power-tree cost and design effort low where efficiency is not the binding constraint. Selection advice: the -3.3 suffix fixes the output voltage — the AMS1117 family also ships in adjustable and other fixed-voltage versions that are not interchangeable, so match the full code. As a linear regulator it dissipates excess voltage as heat, so verify your input-to-output differential and load current against thermal limits, and consider a switching regulator where efficiency matters. This is another heavily counterfeited commodity part: require lot and date-code traceability.

AP2112K-1.2TR-G1 is a Diodes Incorporated AP2112 fixed 1.2 V low-dropout regulator — 600 mA output, CMOS design with enable pin, 55 µA quiescent current, in SOT-25, tape-and-reel packing (TR), -40 to +85 °C. The 1.2 V fixed output is the selection point: a ready-made core-voltage rail for MCUs, FPGAs and RF modules from a 2.5-6 V input, with enable control for power sequencing. Selection advice: the enable pin with discharge resistor simplifies sequencing — tie it high only if you truly never need shutdown. The 600 mA rating suits digital cores and sensors; for higher current choose a larger LDO family. Note the G1 suffix is the green (lead-free) variant and TR is reel packing. Evidence: Diodes AP2112 datasheet and distributor listings confirm 600 mA, 1.2 V fixed, SOT-25 and reel packing. Match the full AP2112K-1.2TR-G1 code for voltage, package and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AP2112K-1.8TRG1 is a Diodes Incorporated AP2112 fixed 1.8 V CMOS low-dropout linear regulator — 600 mA guaranteed, enable pin with auto-discharge, in SOT-25, tape-and-reel packing, 2.5 to 6 V input, -40 to +85 °C. The 250 mV typical dropout at 600 mA with ±1.5% output accuracy is the selection point: a true 1.8 V core rail from a 3.3 V or 5 V bus in a 5-pin SOT-25. Selection advice: the enable pin plus the 60 Ω auto-discharge is the feature to design around — when disabled the output is actively pulled to ground, giving clean power sequencing instead of a floating rail that back-powers downstream logic. With 55 µA quiescent and 0.01 µA standby current it suits battery-powered 1.8 V MCU, FPGA-core and memory rails; for 2.5 V rails use the AP2112K-2.5TRG1 sibling rather than this 1.8 V code. The TRG1 suffix is tape and reel for SMT production. Evidence: Diodes AP2112 datasheet and Farnell/element14 listings confirm 1.8 V, 600 mA, enable with auto-discharge, SOT-25 and 2.5-6 V input. Match the full AP2112K-1.8TRG1 code for voltage and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
