HM3420 - N-Channel Enhancement Mode Power MOSFET

General Description

The HM3420 is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 2A of output current.

The device operates from an input voltage range of 2.5V to 6.0V and provides an output voltage from 0.6V to VIN, making the HM3420 ideal for low voltage power conversions.

Key Features

  • High Efficiency: Up to 97%.
  • Capable of Delivering 2A.
  • 1.3MHz Switching Frequency.
  • No External Schottky Diode Needed.
  • Light-load Mode.
  • Internal Compensation and Soft-Start.
  • Current Mode control.
  • 0.6V Reference for Low Output voltages inductors, while still providing low output ripples. This low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making HM3420 an ideal green replacement for large power consuming.
