MT3406 - Synchronous Step-Down Converter

General Description

The M3406 is a constant frequency, current mode step-down converter.

The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode.

It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery.

Key Features

  • High Efficiency: Up to 96%.
  • 1.5MHz Constant Frequency Operation.
  • 800mA Output Current.
  • No Schottky Diode Required.
  • 2V to 6V Input Voltage Range.
  • Output Voltage as Low as 0.6V.
  • PFM Mode for High Efficiency in Light Load.
  • 100% Duty Cycle in Dropout Operation.
  • Low Quiescent Current: 20μA.
  • Slope Compensated Current Mode Control for Excellent Line and Load Transient Response.
  • Short Circuit Protection.
  • Thermal Fault Protection.
  • Inrush C.
