The MP8760D is a fully integrated high frequency synchronous rectified step-down switch mode converter. It offers a very compact solution to achieve 6A output current over a wide input supply range with excellent load and line regulation. The MP8760D operates at high efficiency over a wide output current load range.
The MP8760D 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 and the frequency keeps nearly constant as input supply varies with the feedforward compensation.
The default under voltage lockout threshold is internally set at less than 4.1V, but a resistor network on the enable pin can increase this threshold. An open drain power good signal indicates that the output is within nominal voltage range.
The MP8760D employs a programmable soft start and shut-down scheme. With the soft shut-down feature, it discharges the output voltage smoothly when the enable signal is deserted.
It has fully integrated protection features that include over-current protection, over-voltage protection and thermal shutdown.
The MP8760D requires a minimal number of readily available standard external components and is available in a 3mm×4mm package.

The EV8760D-L-00A is an evaluation board for the MP8760DGL, a high-efficiency, monolithic, synchronous, step-down converter with output discharge function.
The EV board can deliver a continuous 6A load current over an 8V-to-18V operating input range. The EV board can achieve high efficiency over a wide output current load range.
Constant-On-Time (COT) control provides fast transient response and eases loop stabilization.
This EV board can be turned on or shut down via a remote ON/OFF input that is referenced to ground. This input is compatible with popular logic devices.
