Figure 1 Typical Application for XDPL8219
Note: The
SSR CV
output in

Description
The XDPL8219 is a high performance
SSR CV
controller for the high power factor flyback converter. The device operates in
QRMn
to maximize the efficiency and minimize the
EMI
, across a wide load range. It enters
ABM
at light load to prevent audible noise and at the same time achieving no-load standby power as low as < 100 mW. The XDPL8219 detects the input voltage type (AC or constant DC) and adapts its proprietary voltage mode pulse modulator accordingly to enhance the system performance. For AC input, it adapts the pulse modulation to achieve high
PF
(>0.9) and low
THD
(<10%) over wide input and load range. For constant DC input, it adapts the pulse modulation which dithers the switching frequency to lower the EMI over the entire operating range. Infineon's innovative digital power platform maximizes the XDPL8219 performance in a standard DSO-8 package. The XDPL8219 transmits
UART
signals to report the estimated input voltage, estimated line frequency, controller temperature, last error code and input voltage loss indication. In addition, it provides the maximum design flexibility and performance optimization with parameter configuration via UART. Infineon offers the programming tools including an user friendly
Graphic User Interface
for
Personal Computer
s, to configure the XDPL8219 parameters. The device has a built-in 600 V HV start-up cell and also a proprietary start-up sequence to ensure a fast output voltage rise with minimal overshoot.
