Status: In Production
The MIC22200 is a high efficiency, 2A integrated switch synchronous buck (step-down) regulator. The MIC22200 switching frequency is programmable from 800kHz to 4MHz, allowing the customer to optimize their designs either for efficiency or for the smallest footprint. The regulator achieves efficiencies as high as 95% while still switching at 1MHz over a broad load range.
The ultra high speed control loops keep the output voltage within regulation even under the 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 MIC22200 offers a full range of sequencing and tracking options. The Enable/Delay pin, combined with the Power-On-Reset (POR) pin, allows multiple outputs to be sequenced in many ways during turn on and turn off. The Ramp Control™ (RC) pin allows the device to be connected to another device in the MIC22X00 family of products to keep the output voltages within a certain delta V on start up.
This board enables the evaluation of the MIC22200; a high power density, frequency-adjustable synchronous buck regulator. The MIC22200 features integrated 2A MOSFETs, integrated frequency compensation, flexible sequencing and tracking abilities. The board is optimized for ease of testing, with all major components are on a single side. The voltage mode feedback loop is designed to allow high...
