MCP1601 - 500mA Synchronous BUCK Regulator

Description

The MCP1601 is a fully integrated synchronous BUCK (step down) DC/DC converter for battery powered systems.

With an input operating range of 2.7V to 5.5V, the MCP1601 is ideal for applications being powered by one single cell Li-Ion, 2 to 3 cell NiMH, NiCd or alkaline sources.

Features

  • Input Range of 2.7V to 5.5V.
  • 3 Operating Modes: PWM, PFM and LDO.
  • Integrated BUCK and Synchronous Switches.
  • Ceramic or Electrolytic Input/Output Filtering Capacitors.
  • 750 kHz Fixed Switching Frequency.
  • Oscillator Synchronization to 1 MHz PWM Mode.
  • Auto-Switching from PWM/PFM Operation.
  • 100% Duty Cycle Capable for Low Input Voltage.
  • 500 mA Continuous Output Current Capability.
  • Integrated Under-Voltage Lock-.
