Status: In Production
The MIC22700 is a high efficiency, 7A Integrated switch synchronous buck (step-down) regulator. The MIC22700 is optimized for highest efficiency. The device achieves more than 95% efficiency while still switching at 1MHz over a broad range. The device works with a small 1µH inductor and down to 47µF 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. A full range of sequencing and tracking options is available with the MIC22700. 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 a high-efficiency, 7A, integrated, synchronous buck (step-down) regulator. The MIC22700 is optimized for highest power density and achieves over 90% efficiency while switching at 1MHz with only 1μH inductor and 100μF output capacitor. The MIC22700 features integrated 7A MOSFETs, flexible sequencing and tracking abilities. This board enables the evaluation of the MIC22700; a high...
