In Production

Not Recommended for New Designs; see MIC22705YML. 

The Micrel MIC22600 is a high-efficiency, 6A, integrated switch, synchronous buck (step-down) regulator. The MIC22600 is optimized for highest efficiency and achieves more than 90% efficiency, while still switching at 1MHz over a broad load range with only 1µH inductor and down to 47 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 MIC22600 offers a full range of sequencing and tracking options. The EN/DLY pin combined with the Power Good/Power-On-Reset (PG/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 MIC22600 is available in a 24-pin 4mm x 4mm MLF® and thermally enhanced 24-pin ePad TSSOP with a junction operating range from -40°C to +125°C.
