MP2315S
3A, 24V, 500kHz, High-Efficiency,
Synchronous, Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP2315S is a high-efficiency, synchronous,
rectified, step-down, switch mode converter
with built-in, internal power MOSFETs. It is a
next generation of the MP2315. It offers a very
compact solution to achieve 3A continuous
output current over a wide input supply range
with excellent load and line regulation.

The MP2315S uses synchronous mode
operation for higher efficiency over the output
current-load range. Current mode operation
provides fast transient response and eases loop
stabilization.
Full protection features include over-current
protection (OCP), over-voltage protection
(OVP), and thermal shutdown.
