General Description
Features
The MIC2159 is a high efficiency, simple to use
synchronous buck controller ICs housed in a 10-pin MSOP
ePAD package. The MIC2159 switches at 400kHz,
allowing the smallest possible external components and is
designed to drive loads up to 30A. The devices feature
high output driver capability, combined with an all n-

Built-in 3 Ω drivers
The MIC2159 operates from a 3V to 14.5V input and can
be configured to generate output voltages as low as 0.8V.
Efficiencies of over 95% can be achieved within the
smallest possible printed circuit board space area.
The MIC2159 is available in a thermally capable 10-pin
ePAD MSOP package, with a junction operating range
from –40 ° C to +125 ° C.
