PI recently released a new design (DER-471) using InnoSwitch-CE, the latest of PI's InnoSwitch

family of ICs.This 15 W design for adapter applications features all the benefits of secondary side

control with the simplicity of primary side regulation.

1. ±3% CV, ±5% CC regulation
2. Insensitive to transformer variation
3. Transient response - superior to secondary side regulated with opto-coupler
4. Smaller, lower cost output capacitors
