Product overview
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.
