BCT1812 - 1.2A 1.5MHz Synchronous Step-Down Converter

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.

Features

  • 2.5V~5.5V Input Voltage Range.
  • 1.2A Output Current.
  • 1.5MHz Switching Frequency Minimizes the External Components.
  • Up to 95% efficiency.
  • 100% Duty Cycle in Dropout Operation.
  • Output Voltage as Low as 0.6V.
  • No Schottky Diode Required.
  • Internal soft-start.
  • Output short protection.
  • Output Auto-Discharge When EN Low.
  • Thermal protection.
  • SOT-23-5 Packages The BCT1812 is available in a 5-pin SOT-23-5 package, which provides a compact solutio.
