The Future of Analog IC Technology
MPM3810
6V Input, 1.2A Module
Synchronous Step-Down Converter
with Integrated Inductor
DESCRIPTION
The MPM3810 is a step-down module converter
with built-in power MOSFETs and inductor. The
module’s integrated inductor simplifies the power
system design and provides easy, efficient use.
The DC-DC module comes in a small surface-
mount QFN-12 (2.5mmx3.0mmx0.9mm) package
and achieves 1.2A peak output current from a
2.5V to 6V input voltage with excellent load and
line regulation. The output voltage is regulated as
low as 0.6V. For adjustable output, only FB
resistors and input and output capacitors are
needed to complete the design.
The constant-on-time control (COT) scheme
provides fast, transient response and eases loop
stabilization. Fault condition protection includes
cycle-by-cycle current limiting and thermal
shutdown (TSD).
The MPM3810 is ideal for a wide range of
applications including high-performance DSPs,
FPGAs, PDAs, portable instruments, and storage.
