Description

The MIC2199 is a high power 300kHz synchronous buck DC-to-DC controller housed in a small 4mm x 4mm MLF?12-lead package. It 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 MIC2199 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 MIC2199 allow up to 20A of output current capability.

For smaller external components, refer to the 500kHz MIC2198.

The MIC2199 is available in a 12-pin 4mm x 4mm MLF?package with a junction temperature range from ?0 to 125.
