TPS544B20RVFR TI Voltage Regulators - DC DC Switching Regulators
The TPS544B20 is a 20-A synchronous step-down converter with PMBus interface, operating from a 4.5-V to 18-V input and providing an adjustable output from 0.4 V to 5.5 V. It features D-CAP3™ mode control for fast transient response, integrated low RDS(on) MOSFETs, and includes telemetry for current, voltage, and temperature monitoring. Packaged in a 40-pin QFN (RVF) (5 mm × 7 mm), it is ideal for high-density point-of-load (POL) conversion in servers, storage systems, and telecom equipment requiring digital power management.
