Monolithic Power Systems MPQ8636GLE-4

Beschreibung

The MPQ8636 is a fully-integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution to achieve 4A/10A/20A output current over a wide input supply range, with excellent load and line regulation. The MPQ8636 operates at high efficiency over a wide output-current–load range. The MPQ8636 uses Constant-On-Time (COT) control to provide a fast transient response and ease loop stabilization. An external resistor programs the operating frequency from 200kHz to 1MHz, and the frequency keeps nearly constant as input supply varies with the feed-forward compensation.
