The RT7203BT is a programmable controller with integration of super charge protocols, and the built-in feedback compensation. An internal MCU is designed in to handle various proprietary protocols via the D+/D- interface.
This controller is a specific design with high integration for off-line AC-DC converters possessing high power density. The RT7203BT integrates a constant voltage loop, a constant current loop and the built-in compensation in feedback control to better regulate the design, this IC not only possesses a feature of component saving via its feedback compensation, but also provides an enhanced transient response and safety protections via the integration of diverse functions.
In applications of high precision control, dual operational amplifiers are adopted in the Digital-to- Analog Converter (DAC) to provide reference voltages used for regulation of voltage loop and current loop in programming the constant voltage (CV) and the constant current (CC), respectively.
