Product Descriptions

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 percent 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.
