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.



FEATURES

* 2.5V~6V Input Voltage Range

* Low R_DS(ON)for Internal Switch: 140/90 mΩ (Top/Bottom)

* 1MHz Switching Frequency

* Internal Soft-Start Limits the Inrush Current

* Internal Compensation Function

* 100% Dropout Operation

* Input Over Voltage Protection

* Over Current Protection

* Short Circuit Protection

* Over Temperature Protection with Auto Recovery
