ST-ONE数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 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.
