MP8770

MP8770

17V, 8A, 700kHz, High-Efficiency, Synchronous, Step-Down

Datasheet

Description

The MP8770 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP8770 offers a very compact solution that achieves 8A of continuous output current with excellent load and line regulation over a wide input range. The MP8770 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 MP8770 requires a minimal number of readily available, standard, external components and is available in a space-saving QFN-16 (3mmx3mm) package.
