MIC22600

1MHz 6A Integrated Switch

Synchronous Buck Regulator

General Description

Features

The Micrel MIC22600 is a high efficiency 6A Integrated

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 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 MIC22600. 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.
