MIC22601

In Production

The Micrel MIC22601 is a high efficiency 6A Integrated switch synchronous buck (step-down) regulator. The MIC22601 is optimized for highest efficiency (greater than 90%), while still switching at 4MHz over a broad load range with only 0.22 µH inductor and down to 22µF 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 MIC22601. The enable/delay pin, combined with the power good 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 MIC22601 is available in a 24-pin 4mm x 4mm MLF® package with a junction operating temperature range from -40°C to +125°C.
