The RT7202KLA is a programmable controller with high integration, including the internal feedback compensation and V2 (regulated voltage for internal MCU) inside. An internal MCU is designed to meet proprietary protocols via the CC1/CC2/D+/D- interface. This controller is a specific design for off-line AC-DC converters to achieve the high power density of a fast charge system. The RT7202KLA can share the output power through Master/Slave I<sup>2</sup>C communication. The built-in feedback compensation not only reduces the external components, but also enhances the transient response. For the safety consideration, the RT7202KLA provides comprehensive protections, including LPS protection and accurate internal Over-Temperature Protection (OTP).<br /> 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).
