The MP2386 is a fully integrated, high-
frequency, synchronous, rectified, step-down,
switch-mode converter. The MP2386 offers a
super-compact solution that achieves 8A of
continuous output current over a wide input
The MP2386 operates at high efficiency over a
wide output current load range based on MPS’s
proprietary switching loss reduction technique
and internal low RDS(ON) power MOSFETs.
Adaptive constant-on-time (COT) control
provides fast transient response and eases loop
stabilization. The DC auto-tune loop combined
with the remote differential sense provides good
load and line regulation.
Full protection features include over-current
protection (OCP), over-voltage protection
(OVP), under-voltage protection (UVP), and
The converter requires a minimal number of
external components and is available in a QFN-
11 (2mmx2mm) package.
