MIC2198 Micrel, Inc. MIC2198
500kHz 4mm Г— 4mm Synchronous Buck Controller General Description Features The MIC2198 is a high-power 500kHz synchronous buck
DC-to-DC controller housed in a small 4mm Г— 4mm MLFв„ў
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 for point-of-load DC-to-DC
conversion in 5V, 12V and higher systems.
The 500kHz 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.
