PJ3406 - 1A Synchronous Step-Down Converter

General Description

The PJ3406 is a constant frequency, current mode PWM 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.
  • 1A Output Current.
  • No Schottky Diode Required.
  • 2.0V to 5.5V Input Voltage Range.
  • Output Voltage as Low as 0.6V.
  • 100% Duty Cycle in Dropout.
  • Low Quiescent Current: 20µA.
  • Slope Compensated Current Mode Control for Excellent Line and Load Transient Response.
  • Short Circuit Protection.
  • Thermal Fault Protection.
  • Inrush Current Limit and Soft Start.
