MT3420 - 2A Synchronous Step-Down Converter

General Description

The MT3420 is a 1.4MHz constant frequency, current mode step-down converter.

It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions.

Key Features

  • High Efficiency: Up to 96%.
  • 1.4MHz Constant Frequency Operation.
  • 2A Output Current.
  • No Schottky Diode Required.
  • 2.5V to 5.5V 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: 40µA.
  • Slope Compensated Current Mode Control for Excellent Line and Load Transient Response.
  • Short Circuit Protection.
