LMR51450SDRRR TI Voltage Regulators - DC DC Switching Regulators
The LMR51450 is a 5 A synchronous step-down converter with wide input voltage range of 4.5 V to 36 V, operating at 1.1 MHz fixed switching frequency. It features integrated high-side and low-side MOSFETs, internal compensation, and a precision enable for programmable UVLO. Packaged in a 12-pin WSON (DRR) (3 mm × 3 mm) with PowerPAD, it is ideal for industrial and automotive point-of-load (POL) applications requiring high current in a compact footprint. Applications include 12 V and 24 V distributed power systems, battery management systems (BMS), industrial sensors, and factory automation.
