Description
General part information
MIC22400 Series
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.
