MIC22602
1MHz, 6A Integrated Switch High
Efficiency Synchronous Buck Regulator General Description
The Micrel MIC22602 is a high efficiency 6A Integrated
switch synchronous buck (step-down) regulator. The
MIC22602 is optimized for highest efficiency, achieving
more than 95% efficiency while still switching at 1MHz
over a broad range. The device works with a small 1ВµH
inductor and 100ВµF 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 MIC22602 offers a full range of
sequencing and tracking options. The EN/DLY pin
combined with the Power Good/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 ∆V on start up.
The MIC22602 is available in a 24-pin 4mm x 4mm MLFВ®
with a junction operating range from –40В°C to +125В°C. …
