DUAL CHANNEL 1A HIGH

EFFICIENCY STEP-DOWN

DC/DC CONVERTER



DESCRIPTION

The UTC UC3666 is a dual channel high efficiency step-down

DFN3030-10

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,

portable instruments, slim-type DVD, microprocessors and DSP

core supplies, wireless and DSL card, PDAs, smart phones,

cellular telephones and so on.


