Overview
RT7202KLA Programmable Multi-Protocol Controller for 20V Output with Power Sharing General Description 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 I2C 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).
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).
