Evaluation Board for SiC451

SIC451EVB-A is a microBUCK® evaluation board. microBUCK® evaluation board is a power management IC development tool for the SiC451 PMBus 1.3 compliant. The SiC451 is a PMBus 1.3 compliant non-isolated DC/DC buck regulator with integrated MOSFETs. It is capable of supplying up to 25A continuous output current.

The SiC45x constant on-time architecture also provides a very fast response to transient voltages, with minimum output capacitance and tight ripple regulation over a broad range of loads. It also enables loop stability regardless of the type of output capacitor used.
