ST-ONEMP Overview
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-plementary active clamp flyback converters to create high power density chargers and adapters with a first USB-PD interface and a second output. The device includes an active...
