Description

The UCC33420EVM-080 is intended to allow designers to evaluate the performance and capabilities of UCC33xx0 family of automotive and industrial devices. UCC33420 is an isolated DC/DC converter module able to deliver 1.5W with 3kVrms of isolation in a very small and compact 4mmx5mmx1mm VSON-12 package, reducing footprint and providing a high-power density. UCC334x0 devices can operate from 4.5V to 5.5V and UCC330x0 from 3.0V to 5.5V at the input side. UCC33x20 devices can regulate the secondary side to 5V or 5.5V and UCC33x10 to 3.3V or 3.7V configuring the SEL pin. This EVM demonstrates typical isolated bias supply voltages used in automotive and industrial applications.
