The MP8638 is a fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter. It offers an ultra-compact solution that can achieve up to 12A of continuous output current (I_OUT), with an adjustable current limit (I_LIMIT).

MPS's proprietary switching loss reduction technique and internal, low on resistance (R_DS(ON)) power MOSFETs allow the device to operate at high efficiency across the entire I_OUT load range.

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

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

The MP8638 requires a minimal number of standard external components, and is available in a QFN-16 (3mmx3mm) package.
