Status: In Production
The MIC22400 is a high-efficiency, 4A integrated switch synchronous buck (step-down) regulator. The MIC22400 is optimized for highest efficiency, achieving over 90% efficiency while still switching at 1MHz over a broad load range. 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 MIC22400 gives a full range of sequencing and tracking options. The EN/DLY pin combined with the Power-On-Reset (POR) pin allows multiple outputs to be sequenced in any way on turn-on and turn-off. The Ramp Control™ (RC) pin allows the device to be connected to another MIC22400 family of products to keep the output voltages within a certain ∆V on start-up.
The MIC22400 is thermally-enhanced 20-pin ePad TSSOP with a junction operating range from -40°C to +125°C.
This board enables the evaluation of the MIC22400; a high-power density, frequency-adjustable synchronous buck regulator. The MIC22400 features, integrated 4A MOSFETs, integrated frequency compensation, flexible sequencing and tracking abilities. The board is optimized for ease of testing, so all major components are on a single side. The voltage mode feedback loop is designed to allow high...
