MIC22705 - 1Mhz, 7A Integrated Switch High-Efficiency Synch Buck Regulator
1MHz, 7A Integrated Switch High-Efficiency
Synchronous Buck Regulator General Description Features The Micrel MIC22705 is a high-efficiency, 7A integrated
switch synchronous buck (step-down) regulator. The
MIC22705 is optimized for highest efficiency, achieving
more than 95% efficiency while still switching at 1MHz.
The ultra-high speed control loop keeps the output voltage
within regulation even under the 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 Controlв„ў (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 в€†V on start-up.
The MIC22705 is available in a 24-pin 4mm x 4mm MLF
with a junction operating range from вЂ“40В°C to +125В°C.
