MIC22700
1MHz, 7A Integrated Switch HighEfficiency Synchronous Buck Regulator General Description
The Micrel MIC22700 is a high-efficiency, 7A, integrated
switch, synchronous buck (step-down) regulator. The
MIC22700 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 MIC22700 offers a full range of
sequencing and tracking options. The Enable/Delay 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.
