MIC22705
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 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 o...
