The RT7208EB is a programmable USB PD controller with built-in functions of synchronous rectification, bi- direction control and internal feedback compensation. The controller MCU handles various proprietary protocols via the D+/D- interface and supports USB PD Type-C via the CC1/CC2 pins. </p>The RT7208EB provides the highly integrated solution for the off-line high power density AC-DC converter by utilizing the zero-voltage switching (ZVS) on main switch. This is accomplished by built-in compensation for feedback control to regulate output voltage and current. In order to reduce usage of external components, the controller is built-in with a synchronous rectification controller, and integrated with diverse functions and protections. These features improve the efficiency as well as the safety of a power converter. </p>In the IC, an internal synchronous rectifier controller can optimize efficiency and provide safe operation in both continuous-conduction mode (CCM) and discontinuous -conduction mode (DCM) under a wide output voltage range of 3.0V to 22V. </p>Moreover, a dual operational amplifier with the digital- to-analog converter (DAC) is embedded for voltage- loop and current-loop regulation when programming the constant-voltage (CV) and constant-current (CC) regulation in high precision.</p>
