The RT7209 is a highly integrated programmable controller, featuring internal feedback compensation and a V5 (regulated voltage for internal MCU). Its wide operation voltage range, from 3.3V to 53V, supports USB PD3.1 SPR and EPR 48V specifications.An internal MCU is designed to meet standard USB PD protocols, Universal Fast Charging Specification (UFCS) and proprietary protocols. This controller is a specifically designed for off-line AC-DC converters to achieve high power density in fast charge systems. The built-in feedback compensation not only reduces the need for external components but also enhances the transient response. For safety considerations, the RT7209 provides comprehensive protections.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
