ST-ONE Digital Controllers

STMicroelectronics ST-ONE Digital Controllers combine an ARM Cortex M0+ core, an offline programmable controller, and USB PD PHY in a single package. The system is designed to control ZVS non-complementary active clamp flyback converters. This creates high-power-density battery chargers and adapters with a USB-PD interface. The devices include an active clamp flyback controller and its HV startup on the primary side. It also includes 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. The STMicroelectronics ST-ONE Digital Controllers are housed in a compact SSOP-36 package ideal for space-constrained applications.
