MP8770C

3V to 17V, 8A, Synchronous Step-Down Converter with Forced CCM

Datasheet

Description

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.
