Tagore Technology is pleased to announce a partnership with Inventchip to introduce a new compact 500 W power supply reference design solution with a Totem Pole PFC front-end and an LLC back-end. Tagore Technology has been delivering disruptive GaN semiconductor solutions for more than 12 years.
The reference design uses Tagore’s TP44100SG (90 milli-ohm) and Inventchip’s CCM Totem Pole controller IC IVC1102/1104 in the front-end PFC section.
The ready-to-use, high-performance solution is well-suited for eBike, adapter, server, power tools charger, and telecommunication power supplies, and delivers the highest efficiency solution in this class at 96.7% peak.
Key specifications
- Universal input voltage support 90 V - 265 Vac
- Output voltage 48 V
- CCM Totem Pole PFC efficiency of greater than 99%
- LLC efficiency > 97.5%
- Overall efficiency 96.7%
- High power density of 20 W / in3
- Less than 30°C temperature rise at 90 Vac
“Implementation of CCM Totem Pole PFC in a compact footprint is non-trivial. Tagore and Inventchip teams worked collaboratively to develop a compact, robust, and low-cost solution,” said Dhaval Dalal, system architect at Tagore Technology.
“Tagore team is ready to support customers worldwide to implement this new CCM Totem Pole PFC solution in a compact footprint using Tagore’s GaN and Inventchip’s Totem Pole PFC controller,” said Gary Huang, Head of Business Development for Tagore.
“Wide bandgap devices, GaN and SiC, open the door for highly efficient CCM Totem Pole PFC designs. The availability of the analog CCM Totem Pole Controllers provided by Inventchip closes the gap for high volume production with a compact, robust, and low-cost solution,” said Dr. Zhong Ye, Inventchip CTO.
