Product Descriptions
The MP8761 is a fully-integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution to achieve a 8A output current over a wide input-supply range with excellent load and line regulation. The MP8761 operates at high efficiency over a wide output-current load range.
The MP8761 uses Constant-On-Time (COT) control mode to provide fast transient response and ease loop stabilization.
An external resistor programs the operating frequency from 200kHz to 1MHz. The frequency stays nearly constant as the input supply varies with the feed-forward compensation.
The default under voltage lockout threshold is 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 full integrated protection features that include over-current protection, over-voltage protection and thermal shutdown.
The MP8761 is available in a 3mm×4mm QFN package, and requires a minimal number of readily-available components.
