MIC22601
4 MHz, 6A Integrated Switch
Synchronous Buck Regulator General Description Features The Micrel MIC22601 is a high efficiency 6A Integrated
switch synchronous buck (step-down) regulator. The
MIC22601 is optimized for highest efficiency (greater than
90%), while still switching at 4MHz over a broad load
range with only 0.22ВµH inductor and down to 22ВµF 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. A full
range of sequencing and tracking options is available with
the MIC22601. The enable/delay pin, combined with the
power good PG/POR pin, allows multiple outputs to be
sequenced in any way during turn on 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 О”V on start up.
The MIC22601 is available in a 24-pin 4mm x 4mm MLFВ®
package with a junction operating temperature range from
–40°C to +125°C.
