EVLONEMP, Power Density Board, ST-ONEMP & MASTERGAN4, Power Delivery Controller, Power Management

EVLONEMP is a very high power density board. It is one of the best power density USB power delivery multiport board with a USB Type-A port and a USB Type-C® port supporting PPS. The design supports a wide range of input voltages and can deliver 10W (5V at 2A) 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 start-up 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.
