The RT7216 is a low quiescent current USB Type-C Power Delivery (PD) controller designed for the secondary side of offline AC-DC power converters. Its high level of integration, including control regulators and a built-in blocking N-MOSFET, enables compact and energy-efficient designs. The embedded MCU and Bi-phase Mark Coding (BMC) transmitter manage PD protocol communication, while integrated DAC and ADC modules deliver precise voltage and current regulation. The RT7216 supports output voltages from 3.3V to 21V and output currents up to 5A. Comprehensive protection features, including Limited Power Source (LPS) and Over-Temperature Protection (OTP), ensure system safety and reliability.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
