Summary

The MIC22602 is a high efficiency 6A Integrated synchronous buck (step-down) regulator. The MIC22602 is optimized for highest power density and achieves over 90% efficiency while switching at 1MHz. The MIC22602 features integrated 6A MOSFETs, flexible sequencing and tracking abilities. This board enables the evaluation of the MIC22602. The board is optimized for ease of testing, with all the components on a single side. The voltage-mode feedback loop is designed to allow high bandwidth with just 2 external compensation components. The high-side MOSFET is a P-Channel device, allowing duty cycle control up to 100%. 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 MIC22602 offers a full range of sequencing and tracking options. The EN/DLY pin combined with the POR/PG pin allows multiple outputs to be sequenced in any way on turn-on and turn-off using EN/DLY pin. The RC (Ramp Control™) pin allows the device to be connected to another MIC22602 to keep the output voltages within a certain voltage margin on start up.
