XDPL8210 Digital Flyback Controller IC XDP™ Digital Power Pin configuration 1 Pin configuration
Pin assignments and basic pin description information are shown below. ZCD 1 8 GND PWM 2 7 VCC CS 3 6 UART GD 4 5 HV PG-DSO-8 (150mil)
Figure 3 Pinning of XDPL8210 Table 1 Pin definitions and functions Name Pin Type Function
ZCD 1 I Zero-crossing detection: The ZCD pin is connected to the auxiliary winding via external resistors divider. It is used for zero-crossing detection, primary-side output voltage sensing and input voltage sensing. PWM 2 I
Pulse Width Modulation (PWM)
dimming: The PWM pin is used as a dimming input. The
PWM
frequency should be fixed in the range from 500 Hz to 2 kHz. CS 3 I Current sensing: The CS pin is used for Flyback MOSFET current sensing via external shunt resistor. GD 4 O Gate driver: The GD pin is used for Flyback MOSFET gate drive control via external series resistor. HV 5 I High voltage: The HV pin is connected to the rectified input voltage via external series resistor. The HV pin is used to charge VCC pin voltage during startup and protection, via an internal 600 V startup cell. In addition, it is also used for line synchronization. UART 6 I/O
Universal Asynchronous Receiver Transmitter
configuration: The UART pin is used as the digital interface for parameter configuration. VCC 7 I Operating voltage supply and sensing GND 8 -
