The RTDTTP4200W066A 4.2kW bridgeless totem-pole power factor correction evaluation board enables highly efficient single-phase AC/DC conversion using the latest Renesas Gen IV Plus SuperGaN® FET. The TP65H030G4PWS is a diode-free GaN FET bridge with low reverse recovery charge.
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.Â
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.
The RDK-710 is a board that implements the RDR-710 reference design report for a 12 W dual-output, open-frame power supply for appliances.
The output options are 5 V/1.4 A or 12 V/0.42 A from an input-voltage range of 85 V to 265 V ac. Featuring built-in synchronous rectification, the RDK-710 achieves efficiency of more than 85% at the nominal ac input.Â
No-load input power is less than 10 mW. Standby input power is less than 260 mW at a 5 V/30 mA load.Â
