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. https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2022-06-11 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2022-06-15 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2024-02-15 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2024-06-20 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2024-08-03 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2025-03-06 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2025-06-21 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2025-07-09 https://elecena.pl/product/20981666/st-one-fully-integrated-controller-for-smart-chargers 2025-11-23
