TPSM861257RDXR TI Voltage Regulators - DC DC Switching Regulators
The TPSM861257 is a 3 A, 17 V synchronous step-down converter in a µSIP module with integrated inductors, MOSFETs, and compensation, operating from a 4 V to 17 V input and providing an adjustable output from 0.8 V to 12 V. It features DCS-Control™ for up to 95% efficiency, a 2.4 MHz switching frequency, and includes a power-good output, UVLO, overcurrent, and thermal protection. Packaged in a 7-pin QFN-FCMOD (RDX) (4 mm × 3.3 mm) , it simplifies power supply design. Applications include industrial and automotive point-of-load (POL) conversion, battery-powered systems, and space-constrained designs requiring a small, easy-to-use 3 A power solution.
