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.
