STMicroelectronics, Resonant Controller 36-Pin, SSOP36 ST-ONE

The STMicroelectronics product is the worlds 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 PD 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-PD communication on the secondary side.

ZVS non complementary active clamp flyback controller with synchronous
rectification and USB PD 3.1 PPS interface
ARM 32 bit Cortex M0+ MCU with 64 kB flash memory for digital power
control and USB protocol
Reinforced galvanically isolated dual communication channel compliant with IEC 62368
