UC3666 Datasheet Dual Channel 1a High Efficiency Step-down DC/dc Converter

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD UC3666 DUAL CHANNEL 1A HIGH EFFICIENCY STEP-DOWN DC/DC CONVERTER.

General Description

The UTC UC3666 is a dual channel high efficiency step-down DC/DC converter with constant frequency and current mode.

A main switch and a synchronous rectifier for high efficiency are contained in each converter, and thus an external Schottky diode is saved.

The output voltage can be adjusted to as low as 0.6V.

Key Features

  • S.
  • high efficiency.
  • Current mode operation.
  • Input voltage varying from 2.5V to 5.5V.
  • Output current on each channel: 1A.
  • Fixed frequency operation.
  • 0.6V reference allows low output voltages.
  • Over-temperature protection circuit.
  • RoHS Compliant (100% green available).
