Product Description

The EV8771-Q-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP8771, a fully-integrated high-frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 10A continuous output current over a wide input range, with excellent load and line regulation. The MP8771 has synchronous-mode operation for higher efficiency over the output current-load range.

Constant On-Time control operation provides very fast transient response and easy loop design as well as very tight output regulation.

Full protection features include SCP, OCP, UVP, and thermal shutdown.

The MP8771 requires a minimal number of readily-available, standard, external components and is available in a space-saving QFN-16 (3mm?3mm) package.

IC Details

The MP8771 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP8771 offers a very compact solution that achieves 10A of continuous output current with excellent load and line regulation over a wide input range. The MP8771 uses synchronous mode operation for higher efficiency over the output current load range.
Constant-on-time (COT) control operation provides very fast transient response, easy loop design, and very tight output regulation.
Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.
The MP8771 requires a minimal number of readily available, standard, external components and is available in a space-saving QFN-16 (3mmx3mm) package.
