TPS65262-1RHBR
The TPS65262-1 integrates three synchronous buck converters (3 A, 1 A, 1 A) from a 4.5 V to 18 V input with adjustable 0.6 V to 17 V outputs, plus two adjustable LDOs (350 mA and 150 mA). Features include power-good, soft-start, adjustable current limit, UVLO and light-load efficiency, operating from -40 C to 85 C. It is designed for multi-rail power in industrial and communication equipment.
