Micrel, Inc. MIC2199 MIC2199
300kHz 4mm Г— 4mm Synchronous Buck Converter General Description Features The MIC2199 is a high-power 300kHz synchronous buck
DC-to-DC controller housed in a small 4mm × 4mm MLF™
12-pin 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.
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 in a 12-pin 4mm × 4mm MLF™
package with a junction temperature range from –40°C to
125В°C. 4.5V to 32V input range
