Product Information

Back to top
The MP8756 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution that achieves 6A of continuous output current with excellent load and line regulation over a wide input supply range.

The MP8756 operates with high efficiency over a wide output-current load range based on MPS’ proprietary switching loss reduction technique and internal low RDS(ON) power MOSFETs.

Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization. The DC auto-tune loop provides good load and line regulation.

Full protection features include over-current limit, over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown.

The converter requires a minimum number of external components and is available in a QFN-12 (2mmx3mm) package.

Symmetry Electronics is an authorized Monolithic Power Systems distributor.
