The RT7209, RT7209B, and RT7209C (RT7209 series) are highly integrated programmable controllers, featuring internal feedback compensation and a V5 (regulated voltage for internal MCU). With a wide operating voltage range from 3.3V to 53V,RT7209 series support USB PD3.2 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 series provide comprehensive protections.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
