General Description
The MIC2199 is a high-power 300kHz synchronous buck DC-to-DC controller housed in a small 4mm × 4mm MLF™ 12-lead 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
