REF_5BR4780BZ-1 15W1 REF_5BR4780BZ-1_15W1 is a reference board using the latest CoolSET™ 5th Generation Fixed Frequency Plus ICE5BR4780BZ-1 switching controller.

Overview

This 15 W auxiliary power supply reference design configured in a non-isolated flyback topology and is based on the ICE5BR4780BZ-1, a product of Infineon’s latest CoolSET™ 5th Generation Fixed Frequency Plus family.

Thanks to the integrated 800 V MOSFET in DIP-7 package, such a design enables the deployment to unstable grid environments and increases system robustness.
