详细说明

The XDP™ digital power XDPL8219 is a high-performance secondary-side regulated flyback controller with high power factor and constant voltage output.

The device operates in quasi-resonant mode (QRM) to maximize the efficiency and minimize the electromagnetic interference (EMI) over a wide load range. It enters active burst mode (ABM) at light load to prevent audible noise from being heard, while achieving no-load standby power as low as <100mW.

The XDPL8219 detects the input voltage type (AC or constant DC) and adjusts its proprietary voltage- mode pulse modulator accordingly to enhance the system performance. For AC input, it adjusts the pulse modulation for achieving a high power factor (PFC >0.9) as well as low total harmonic distortion (THD <10%). For a constant DC input, it adapts the pulse modulation, thereby adjusting the switching frequency to reduce EMI over the entire operating range.

The device provides maximum design flexibility and performance optimization through parameter configuration via the Universal Asynchronous Receiver Transmitter (UART) pin. The XDPL8219 transmits signals to report parameters such as input voltage, line frequency, controller temperature, last error code, and input voltage loss indication. The programming tools provided by Infineon include a user-friendly graphic user interface (GUI) for the PC for configuring the parameters of XDPL8219. The device is housed in a DSO-8 package, with a built-in 600V HV start-up cell and a proprietary start-up sequence, ensuring a fast output voltage rise with minimal overshoot.
