General Description
The MIC22705 is a highly efficient, 7A, integrated
switch, synchronous buck (step-down) regulator. The
MIC22705 is optimized for highest efficiency, achieving
more than 95% efficiency while still switching at 1 MHz
over a broad range. 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 is
pre-bias safe and can be adjusted down to 0.7V to
address all low-voltage power needs.
The MIC22705 offers a full range of sequencing and
tracking options. The Enable/Delay (EN/DLY) pin,
combined with the Power Good (PG) pin, allows
multiple outputs to be sequenced in any way during
turn-on and turn-off. The Ramp Control (RC) 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 MIC22705 is available in a 24-pin 4mm x 4mm
QFN with a junction operating range from –40°C to
+125°C.
