Digital high-power-factor XDP™ controller for cost-effective, dual-stage LED drivers with secondary-side regulated constant voltage output

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 TLD5045 is a highly integrated smart LED buck converter with built in protection functions

The main function of this device is to drive single or multiple series connected LEDs efficiently from a voltage source higher than the LED forward voltage by regulating a constant LED current. The constant current regulation is especially beneficial for LED color accuracy and long LED lifetime. The built in freewheeling diode and switching transistor with current sense requires less external components and saves system costs. High flexibility is achieved by placing low power resistors to adjust output currents up to 700mA and the regulator switching frequency (typ. 200kHz). An integrated PWM dimming engine provides a LED dimming function by placing a simple RC network to GND. This feature is dedicated for decentralized light modules without microcontroller involvement. In addition to that an integrated status pull down transistor can be used to simulate a minimum current flow for decentralized modules to avoid a wrong open load detection by a highside switch located in the body control module (BCM).
