TPS54302DDCR

TPS560430XDBVR is a Texas Instruments 36V, 4A synchronous buck converter — for industrial and automotive power rails: 4A continuous output current, up to 36V input, synchronous rectification for high efficiency, SOT-23-6 package. The synchronous topology eliminates the external Schottky diode, so efficiency stays high across the load range while the BOM shrinks; the 36V input rating tolerates 24V industrial buses with margin for transients. Business impact: compact high-current bucks are the default choice for point-of-load regulation — the SOT-23-6 footprint fits where larger packages cannot, and TI availability keeps lead times manageable. Selection advice: the XDBVR code denotes SOT-23-6 on tape and reel — verify the switching frequency and compensation against the TI datasheet for your specific input/output combination. Ranked #11 on the hqbuy.com real-time hot list (2026-10-05). Parameters verified against Texas Instruments documentation.

LM5164DDAR is a Texas Instruments 100 V input synchronous buck converter in SOIC-8, tape and reel — for industrial power supplies: 48 V bus step-down, PoE front ends and motor-drive auxiliaries. The 100 V input rating is the selection point: direct operation from high-voltage industrial buses that standard 60 V bucks cannot survive. Selection advice: the DDAR suffix denotes SOIC-8 in tape and reel for production — plan the external MOSFET, inductor and compensation network per TI's reference design; this is a controller-class part, not a module. For lower-voltage rails, cheaper integrated bucks save board space. Parameters verified against the TI official product page.

TLV62568DBVR is a Texas Instruments 1 A synchronous step-down buck converter in SOT-23-5 (DBV), tape-and-reel packing (R) — 2.5 V to 5.5 V input, adjustable output from 0.6 V up to VIN, up to 95% efficiency, 35 µA operating quiescent current, 1.5 MHz typical switching frequency, power-save mode for light-load efficiency, 100% duty cycle for lowest dropout, internal soft start, overcurrent and thermal-shutdown protection, −40 to +125 °C. The adjustable output with 100% duty cycle is the selection point: one part generates 1.2 V, 1.8 V, 3.3 V or any logic rail from a 5 V or Li-ion source with near-zero dropout, so the same footprint covers multiple rails across a board — a general-purpose point-of-load workhorse for set-top boxes, cameras, routers and disk drives. Selection advice: the DBV is the 5-pin SOT-23; the R suffix is tape and reel. The adjustable TLV62568 covers what the fixed-output members of the family do plus any custom rail — confirm the exact fixed-output code only if the BOM specifies one. TI lists TLV62568DBVR as Active. Evidence: TI TLV62568 datasheet (SLVSD89) and distributor listings confirm 1 A, 2.5–5.5 V, 0.6 V to VIN, SOT-23-5 and tape-and-reel packing. Match the full TLV62568DBVR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS56221DQPR is a Texas Instruments 25A synchronous buck converter — for high-current point-of-load supplies: 4.5V to 14V input, output down to 0.6V at up to 25A, integrated NexFET power MOSFETs, fixed-frequency options of 300kHz, 500kHz and 1MHz, voltage-mode control with feed-forward, 600mV reference with 1% accuracy, programmable soft start, resistor-programmed overcurrent protection, thermal shutdown, 22-pin 5x6mm PQFN PowerPAD package. The integrated NexFET power block delivers 25A from a 30mm² footprint, so FPGA and processor core rails fit tight board areas; feed-forward compensation responds instantly to input voltage changes. Business impact: high-current POL converters are critical-path components in server and telecom designs — a stocked, well-documented part accelerates power-tree qualification. Selection advice: the DQPR code is the PQFN-22 package in tape and reel — verify the overcurrent protection programming resistor and loop compensation against the TI datasheet for the target load transient.

The MIC28517T-E/PHA is a Microchip Technology 70 V, 8 A Hyper Speed Control synchronous buck regulator in a 32-pin 6 mm by 6 mm VQFN. Its 4.5 V to 70 V input range and adjustable 0.6 V to 32 V output with +/-1 percent feedback accuracy cover 12 V, 24 V and 48 V industrial and telecom rails from a single device, which consolidates inventory and simplifies platform power design. The adaptive on-time architecture gives ultra-fast transient response with small output capacitance, and a pin-selectable HyperLight Load or forced continuous-conduction mode keeps light-load efficiency high. Adjustable 270 kHz to 800 kHz switching, internal compensation, a built-in 5 V regulator, auxiliary bootstrap LDO, programmable current limit, hiccup short-circuit protection and thermal shutdown reduce external component count and protect the load, supporting safe start-up into a pre-biased output. It operates from -40C to +125C junction temperature. Selection advice: this variant carries the MODE pin for HLL versus CCM selection; if your design instead needs an externally adjustable soft-start time, choose its sibling MIC28516, which trades the MODE pin for a soft-start pin.

MP9943GQ-Z is a Monolithic Power Systems 3 A synchronous step-down converter, 4 to 36 V input, adjustable output from 0.8 V (792 mV feedback reference), 410 kHz, in a QFN-8 (3 × 3 mm) package — a compact point-of-load regulator for set-top boxes, networking gear and industrial modules. The synchronous architecture is the selection point: integrated high-side and low-side MOSFETs eliminate the external Schottky diode that non-synchronous bucks like the TPS5430 require, cutting BOM count and improving light-to-mid-load efficiency in the same 3 A class. Selection advice: the -Z suffix is MPS tape-and-reel packing (-P is tray/tube), so match the suffix to your assembly line; the EN pin gives simple sequencing/shutdown, the PG output supports power-good monitoring, and the SYNC pin accepts 200 kHz to 2.4 MHz external clocking for EMI-sensitive designs. Rated -40 to +125 °C junction. Do not confuse with the MP9943A variant (different feature set) — verify the exact MP9943GQ-Z code on the MPS datasheet. Parameters verified against the MPS MP9943 datasheet (Rev. 1.1) and distributor listings.

LM74700QDBVRQ1 is a Texas Instruments automotive ideal diode controller in SOT-23-6, tape and reel — for reverse-polarity and reverse-current protection in automotive power inputs. Driving an external N-channel MOSFET as an ideal diode is the selection point: near-zero forward drop versus a Schottky, saving watts in high-current feeds. Selection advice: the Q1 suffix denotes the automotive-qualified variant — mandatory for automotive programs; the non-Q1 LM74700 suits industrial designs. Size the external MOSFET for your load current and inrush. Parameters verified against the TI official product page.

TPS2553QDBVRQ1 is a Texas Instruments automotive precision current-limited power-distribution switch in SOT-23-6 — for USB ports and 5 V load switching: adjustable 75 mA–1.7 A current limit via external resistor, ±6% accuracy at 1.7 A, 2.5–6.5 V input, 85 mΩ high-side MOSFET, AEC-Q100 Grade 1 (-40°C to +125°C). The tight current-limit accuracy lets designers set the threshold close to the real load, avoiding nuisance trips while still protecting connectors and cables — fewer field returns than over-conservative polyfuses. Selection advice: the QDBVRQ1 code is the automotive SOT-23-6 tape-and-reel variant — the EN pin is active-high on this version, verify logic against the standard TPS2553; for a fixed 500 mA USB limit consider the TPS2550. Ranked #20 on the Chuangxin Index June 2026 breakout list (1,732 searches, +370.65% MoM). Parameters verified against Texas Instruments documentation.
