Product 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 converter (VOUT) with an adjustable current limit (CLM). 
The MP8720 operates at high efficiency over a wide output current load range based on MPS’s proprietary switching loss reduction technology 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.
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.
