DESCRIPTION

The MP8720 provides a complete power supply

with the highest power density for system

powers, such as DDR memory and USB type-C.

The MP8720 integrates a high-frequency,

synchronous, rectified, step-down, switch-mode

(CLM).

The MP8720 operates at high efficiency over a

wide output current load range based on MPS’s

proprietary switching loss reduction technology

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.

By setting CLM, the current limit can be

adjusted from 8.5A to 16.5A for different mode

applications.

Full protection features include over-current

limit (OCL), over-voltage protection (OVP),

under-voltage protection (UVP), and thermal

shutdown.

The MP8720 requires a minimal number of

external components and is available in a QFN-

16 (3mmx3mm) package.
