The EVLONE140W is one of the first reference design to be certified according to the USB-PD 3.1 EPR standard. It supports a wide range of input voltages and can deliver four SPR outputs, an EPR output and an AVS output up to 28 V at 5 A.

This board is based on ST-ONEHP digital controller in companion with L6563S (PFC controller) and MasterGaN1 (600 V half-bridge GaN power stage), providing a solution with very high-power density exceeding 25 W/inch3.

ST-ONEHP belongs to ST-ONE family of digital controllers, world’s first embedding ARM Cortex M0+ core, an off-line programmable controller with synchronous rectification, and USB PD PHY in a single package.

Such a system is specifically designed to control ZVS non-complementary Active Clamp Flyback (ACF) converters to create high power density chargers and adapters with USB-PD EPR interface.

The device includes the ACF controller and its HV startup on the primary side, a microcontroller and all the peripherals required to control the conversion and the USB-PD communication on the secondary side. The two sides are connected through an embedded reinforced galvanically isolated dual communication channel.

High switching frequency operations in companion with MasterGaN1 power stage allow to use small size magnetic component and allow reaching a very high efficiency (greater than 94%).
