The MPQ8636HGV-20 is a fully-integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter.

Product Detail

The MPQ8636HGV-20 is a fully-integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution to achieve 20A output current over a wide input supply range, with excellent load and line regulation. The MPQ8636HGV-20 operates at high efficiency over a wide output-current?oad range. The MPQ8636HGV-20 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. The default under-voltage lockout threshold is internally set at 4.1V, but a resistor network on the enable pin can increase this threshold. The soft-start pin controls the output-voltage startup ramp. An open-drain power-good signal indicates that the output is within nominal voltage range. It has fully-integrated protection features that include over-current protection, over-voltage protection and thermal shutdown. The MPQ8636HGV-20 requires a minimal number of readily-available, standard, external components and is available in a 5mm?mm 25-Pin QFN package.
