Product overview


The EVLONEMP is one of the best power density USB Power Delivery multiport boards with a USB Type-A port and a USB Type-C® port supporting Programmable Power Supply (PPS). The design supports a wide range of input voltages and can deliver 10 W (5 V@2 A) on a Type-A port, and five fixed PDOs and two APDOs on a Type-C port.

This board is based on ST-ONEMP, the world’s first digital controller embedding 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 Power Delivery 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 Power Delivery communication on the secondary side. The two sides are connected through an embedded galvanically isolated dual communication channel.

High switching operations in companion with MasterGaN power stage allow to use small size magnetic components and allow to reach a very high efficiency.
