1 / 29 page  MIC22600 1MHz, 6A Integrated Switch Synchronous Buck Regulator Ramp Control is a trademark of Micrel, Inc. MLF and MicroLeadFrame are registered trademarks of Amkor Technology, Inc. Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 ( 408) 944-0800 • fax + 1 (408) 474-1000 • http://www.micrel.com October 2009 M9999-102809-C General Description 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 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. The MIC22600 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. The MIC22600 is available in a 24-pin 4mm x 4mm MLF ® and thermally enhanced 24-pin E-Pad TSSOP with a junction operating range from –40 °C to +125°C. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
