MIC2198 Datasheet (Micrel Semiconductor) - 500kHz 4mm x 4mm Synchronous Buck Controller

MIC2198, 500kHz 4mm x 4mm Synchronous Buck Controller

The MIC2198 is a high-power 500kHz synchronous buck DC-to-DC controller housed in a small 4mm × 4mm MLF™ 12-pin package.

The MIC2198 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 MIC2198 an ideal solution
