UC3206X Datasheet

600mA, 3MHz, SYNCHRONOUS STEP-DOWN DC/DC CONVERTER

 

 

 

DESCRIPTION

 

The UTC UC3206X is a high efficiency synchronous, step-down

DC/DC converter. Its input voltage range is from 2V to 6V, and

Output voltage is internally set  in a range from 0.8V to 4.0V in

increments of 50mV (accuracy: ±2.0%).

The device is operated by  3.0MHz, and includes 0.42Ω

P-channel driver transistor and 0.52Ω N-channel switching

transistor. The device provides short-time turn-on by the soft start

function internally set in 0.25 ms (TYP).
