Product overview

Description

The ST-ONE 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 USB-PD interface.

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.

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.

  • All features

    • 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 protocolFW programmable secondary side MCU controls both synchronous rectifier and ZVS Active Clamp flyback on the primary side to improve system efficiency in every conditionHigh switching frequency operations in companion with MasterGaN power stage allow to use small size magnetic components, including planar transformers
    • Reinforced galvanically isolated dual communication channel compliant with IEC 62368:4 kV pk transient voltage9.6 kV pk 1min hipot type testing 6.4 kV pk 1s hipot production testing
    • 800 V high voltage startup with integrated input voltage sensing and Brown-in/out functions
    • Active input filter capacitor discharge circuitry for reduced standby power compliant with IEC 62368-1
    • Fully Integrated USB-PD PHY with 24 V tolerant protection, and integrated load switch driver
