1.2A, 1.5MHz Synchronous Step-Down Converter

BCT1812  
1.2A, 1.5MHz Synchronous Step-Down Converter

GENERAL DESCRIPTION

The BCT1812 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 current limit protection and on-chip thermal shutdown features provide protection against any combination of overload or ambient temperature.

The BCT1812 is available in a 5-pin SOT-23-5 package, which provides a compact solution with minimal external components.
