UC3666 Datasheet (UTC) - DUAL CHANNEL 1A HIGH EFFICIENCY STEP-DOWN DC/DC CONVERTER

UC3666, DUAL CHANNEL 1A HIGH EFFICIENCY STEP-DOWN DC/DC CONVERTER

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 l
