The RT7206KNx series is a USB Type-C Power Delivery (PD) controller, that mainly utilized in the secondary side for off-line AC-DC power converters. Through the high integration of control regulators and built-in blocking N-MOSFET, more compact designs are easily implemented. The embedded MCU solution and Bi-phase Mark Coding (BMC) Transmitter are incorporated to handle PD Protocol. Furthermore, the digital-to-analog (DAC) and analog-to-digital (ADC) converters are introduced to achieve high-precision control in various applications.

The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
