Device Overview

Summary

The MIC2199 is a high power 300kHz synchronous buck DC-to-DC controller. 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 inductor and small output capacitors. The current mode PWM control along with the external COMP pin allows for ease of stability compensation and fast transient response across a wide range of 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. The MIC2199 is available with a junction temperature range from -40°C to 125°C.
