High-Efficiency, 700kHz, 8A, 17V Step-Down Converter Evaluation Board
The EV8770C-Q-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP8770C, a fully-integrated highfrequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs.It offers a very compact solution to achieve a 8A continuous output current over a wide input range, with excellent load and line regulation. The MP8770C has synchronousmode 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 MP8770C requires a minimal number of readily-available, standard, external components and is available in a space-saving QFN-16 (3mmх3mm) package.

3V to 17V, 8A, Synchronous Step-Down Converter with Forced CCM
The MP8770C is a fully integrated, high-frequency, synchronous rectified step-down switch-mode converter with internal power MOSFETs. The MP8770C offers a very compact solution to achieve 8A of continuous output current with excellent load and line regulation over a wide input range. The MP8770C uses synchronous mode operation for higher efficiency over the output current load range.
Constant-on-time (COT) control operation provides very fast transient response and easy loop design, as well as very tight output regulation.
Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.
The MP8770C requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-16 (3mmx3mm) package.
