RT7202KNH数据手册Richtek中文资料规格书

描述 Description

The RT7202KNx series is a secondary-side USB Type-C Power Delivery (PD) controller for high-efficiency off-line AC-DC converters. Through the high integration of control regulators and built-in N-MOSFET driver, more compact designs are easily implemented. The embedded MCU solution with Bi-phase Mark Coding (BMC) transceiver is introduced to handle PD and other proprietary protocols. Furthermore, the digital-to-analog converter (DAC) is utilized in serving commands for constant-voltage (CV) and constant-current (CC) regulations to achieve high-precision control in various applications.
