UC3206X中文资料600mA, 3MHz, SYNCHRONOUS STEP-DOWN DC/DC CONVERTER数据手册UTC规格书

描述 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 0.42ΩP-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).
