DUAL CHANNEL 1A HIGH EFFICIENCY STEP-DOWN DC/DC CONVERTER
- 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. With input voltage range from 2.5V ~ 5.5V , each converter can deliver 1A current to the load. Due to the internally fixed 1.6MHz switching frequency, small surface mount inductors and capacitors can be used.
The UTC UC3666 is generally used in digital still cameras,...
