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.
