LT7930AUK#PBF

LT7930AUK#PBF is a 72 V parallelable 4-switch buck-boost controller from Analog Devices for GaN FETs and Si MOSFETs in a 48-lead 7 mm x 7 mm LFCSP, with a 5 V to 72 V input range, 1 V to 72 V output range, up to 99% synchronous-rectification efficiency, and plus-minus 1% output accuracy. Its single-inductor architecture handles input above, below, or equal to the output with seamless low-noise transitions, while 5 V-optimized gate drivers, continuously programmable 0 to 100 ns dead time, phase-lockable 150 kHz to 1 MHz switching, DCR or RSENSE current sensing, programmable input or output current regulation, VIN overvoltage protection, and multiphase/multi-IC parallel operation cover 48 V industrial and telecom rails, distributed DC power, battery backup, and battery charging from one controller. Parallel operation scales output power without a new control architecture, and the programmable current loop supports accurate battery charging. Selection advice: the full orderable code is LT7930AUK#PBF (tape-and-reel LT7930AUK#TRPBF); the LT7930EUH form does not appear in the ADI ordering guide, so do not order by base name alone. Against the LTC7878 (70 V, up to 98%), the LT7930 extends input to 72 V and adds GaN-optimized dead time; against the LT8705A (80 V), it trades top voltage for parallel and GaN operation. Set dead time for GaN (short) or Si MOSFETs (longer) by resistor, and verify layout against the ADI datasheet. ADI lists the part as recommended for new designs, while its Rev 0 datasheet (July 2026) is marked Preliminary, so confirm release status in your RFQ. No price, stock, or lead time is stated here; send your quantity, packing, and date-code requirements in your RFQ.
