The MIC22602 is a high efficiency 6A Integrated switch synchronous buck (step-down) regulator. The MIC22602 is optimized for highest efficiency, achieving more than 95% efficiency while still switching at 1MHz over a broad range. The device works with a small 1µH inductor and 100µF 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 MIC22602 offers a full range of sequencing and tracking options. The EN/DLY 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.
