ST-ONEMP Overview
Key Specifications
Description
The ST-ONEMP 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 a first USB-PD interface and a second output.
Key Features
- ZVS non-complementary active clamp flyback controller with synchronous rectification and USB-PD 3.1 PPS interface
- 800 V high voltage startup with integrated input voltage sensing and Brownin/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
