The TPS546D24SRVFR is a single-output step-down buck converter rated for 40 A continuous output current — enough to power a modern FPGA core rail or a multi-GHz processor VDD from a 2.95 V to 16 V input bus. The output voltage is programmable from 0.25 V up to 5.5 V, and the switching frequency spans 225 kHz to 1.5 MHz, letting you trade off inductor size against ripple.
The TPS546D24SRVFR is rated for 40 A continuous output current, single output, with synchronous rectification.
