The RT7206A is a programmable controller with a high integration of the internal feedback compensation, blocking N-MOSFETs and the current sense. An internal MCU is designed to handle various proprietary protocols via the D+/D- interface and support the Type-C USB PD via the CC1/CC2 pins.
This controller is a specific design with high integration for off-line AC-DC converters to possess the high power density. The RT7206A integrates a constant voltage loop, a constant current loop and the built-in compensation in the feedback control so as to regulate output voltage and current. With the proprietary design, this controller not only possesses the feature of component-count saving via the built-in feedback compensation, but also provides the performance of enhanced transient response and safety level via the integration of diverse functions and protections.
In applications requiring high-precision control, a dual operational amplifier is adopted in the Digital-to-Analog Converter (DAC) to serve reference voltages used for regulation of voltage loop and current loop in programming the constant voltage (CV) and the constant current (CC).
