30 60VIN ZVS Buck Evaluation Board

This evaluation board is designed for the PI358x family of 7 x 8mm ZVS Bucks.

It can be configured to demonstrate a single product in a standalone local-sense or a remote-sense configuration.

The PI358x family of wide input range DC-DC ZVS Buck regulators feature high efficiency with integrated controller and power switches within a high-density 0.28 x 0.32in GQFN package. Required external components are placed inside a demarcation featuring a solution size of 1.09 x 0.96in. The demarcation includes an external inductor, compensation capacitor, voltage selection resistors, soft-start capacitor and input-output capacitors to form a complete DC-DC regulator.
