The RDK-747 reference design kit from Power Integrations demonstrates a design for a 20 V/3.25 A output charger using the InnoSwitch™3-EP with a 750 V PowiGaN™ power switch. This design shows the high power density and efficiency achieved when using the highly integrated InnoSwitch3-EP ac-dc power converter.
The InnoSwitch3-EP, the industry’s first ac-dc converter IC with isolated, safety-rated integrated feedback, offers all the benefits of secondary-side control with the simplicity of primary-side regulation. Insensitive to transformer variation, the converter features built-in synchronous rectification for high efficiency. The design meets the requirements for compliance with DOE6 and CoC Tier 2 V5 2016.
