Introduction

A high frequency, synchronous buck converter with internal power MOSFET. Supports wide input voltage range: 4.5V to 18V and provides 2.0A continuous load current capability, and provide high efficiency without use of external Schottky diode. Low output voltage ripple and small external inductor and capacitor size are achieved with 600KHz switching frequency.

Has a variety of protection functions: Input over voltage protection, Input UVLO, Output over current protection, Output short protection and thermal shutdown.

Available in a 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
