MIC2199

300kHz 4mm × 4mm Synchronous Buck Converter

General Description

Features

The MIC2199 is a high-power 300kHz synchronous buck

DC-to-DC controller housed in a small 4mm×4mm MLF™

12-pin package. The MIC2199 operates from a wide 4.5V

to 32V input and can be programmed for output voltages

from 0.8V to 6V. The wide input voltage capability makes

the MIC2199 an ideal solution for point-of-load DC-to-DC

conversion in 5V, 12V, 24V, and 28V systems.

The 300kHz switching frequency allows the use of a small

inductorandsmalloutputcapacitors.ThecurrentmodePWM

control along with the external COMP pin allows for ease of

stability compensation and fast transient response across a

wide range of applications.

Applications

An all N-Channel synchronous architecture and powerful

output drivers allow up to 20A of output current capability.

For smaller external components, refer to the 500kHz

MIC2198.
