LINEAR INTEGRATED CIRCUIT
HIGH EFFICIENCY 1MHz 2A SYNCHRONOUS STEP DOWN CONVERTER
DESCRIPTION
The UTC UD052012 is a high efficiency, high frequency synchronous DC-DC step-down converter. The 100% duty cycle feature provides low dropout operation, extending battery life in portable systems.
The internal synchronous switch increases efficiency and eliminates the need for external Schottky diode. At shutdown mode, the input supply current is less than 1µA.
The UTC UD052012 fault protection includes over current protection, short circuit protection, UVLO and thermal shutdown. The Internal soft-start function prevents inrush current at turn-on.
