Description

The EVLONE65W is a high power density USB-PD board supporting Programmable

Power Supply (PPS). The design supports wide range input voltage and can deliver

five fixed PDOs and two APDOs.

This board is based on ST-ONE, the world’s first digital controller embedding an

Arm® Cortex® M0+ core, an offline 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 converters to create high power density chargers and adapters with

USB-PD interface. The device includes an active clamp flyback 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 galvanically isolated dual

communication channel.

High switching frequency operations in companion with a MasterGaN4 power stage

allows use of small size magnetic components while reaching a very high efficiency.
