The RT7204E is a highly integrated, programmable controller that offers multi-protocol support and features high-precision shunt regulators for constant voltage (CV) and constant current (CC) regulation. An embedded MCU is designed to handle customized functions with flexibility, ensuring compatibility with USB PD protocol, Universal Fast Charging Specification (UFCS), and proprietary protocols via the CC1, CC2, D+, and D- interface.
This controller is specifically designed for off-line AC-DC converters to achieve the high power density of a fast charging system. The RT7204E is equipped with rectification detection to sense the AC input voltage and adaptively configure the power rating. Additionally, it monitors the PWM switching state to detect AC OFF conditions. For safety considerations, the RT7204E provides comprehensive protections, including Limited Power Source (LPS) protection and precise internal Over-Temperature Protection (OTP). Furthermore, the RT7204E can also share the output power through I2C communication for multi-port applications.
The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
