MIC22600
1MHz, 6A Integrated Switch
Synchronous Buck Regulator
NOT RECOMMENDED FOR NEW DESIGNS
SEE MIC22705 General Description
The Micrel MIC22600 is a high-efficiency, 6A, integrated
switch, synchronous buck (step-down) regulator. The
MIC22600 is optimized for highest efficiency and achieves
more than 90% efficiency, while still switching at 1MHz
over a broad load range with only 1ВµH inductor and down
to 47ВµF output capacitor. The ultra-high-speed control loop
keeps the output voltage within regulation even under
extreme transient load swings commonly found in FPGAs
and low voltage ASICs. The output voltage can be
adjusted down to 0.7V to address all low voltage power
needs. The MIC22600 offers a full range of sequencing
and tracking options. The EN/DLY pin combined with the
Power Good/Power-on-Reset (PG/POR) pin allows
multiple outputs to be sequenced in any way during turnon and turn-off. The RC (Ramp Controlв„ў) pin allows the
device to be connected to another product in the
MIC22xxx and/or MIC68xxx family, to keep the output
voltages within a certain ∆V on start-up.
