Fully integrated controller for multiport smart chargers

The STMicroelectronics ST-ONEMP is 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 a first USB-PD interface and a second output.

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. By using a novel non-complementary control technique and specifically designed power modes the device allows to reach both high efficiency and low no load power consumption

The device is delivered with a pre-loaded firmware which handles both the power conversion and the communication protocols for USB-PD including optional PPS and electronically marked cable management.

The output power and available PDOs on the USB-PD port can be changed according to a power sharing pin input to allow power sharing with a second output.

A dedicated memory stores a default device configuration during factory process. The user can change or adapt this memory area to fit the final product specifications.
