Description
Ideal for gaming laptops, TVs, displays, and high-performance consumer electronics, this demoboard enables engineers to evaluate a compact, high-density AC-DC converter delivering 20V/15A output at 95% efficiency. Built around WiseGan® WI71060 and WI71120 and driven by the WIW1001 digital controller, it operates at high switching frequencies up to 2 MHz, significantly reducing passive component size and improving thermal management.
Features
Totem Pole PFC (CrCM) + LLCMCU Digital controller WIW1001Using WiseGan® WI71060 for PFC stage and WI71120 for LLC stage switching transistors.Vin: 90-264 VACOutput: 20V / 15A95% efficiency
Typical applications
- gaming laptops, TVs, displays, and high-performance consumer electronics
