The MIC22700 is a highly efficient, 7A, integrated switch, synchronous buck (step-down) regulator. The MIC22700 is optimized for highest efficiency, achieving more than 95% efficiency while still switching at 1 MHz over a broad range. The device works with a small 1 μH inductor and 100 μF 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 Control) 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 MIC22700 is available in a 24-pin 4mm x 4mm QFN with a junction operating range from –40°C to +125°C.
