XDPL8219 Digital Flyback Controller IC XDP™ Digital Power Features
• Flyback controller with
Power Factor Correction (PFC)
•
Secondary Side Regulated (SSR) Constant Voltage (CV)
output • Integrated 600 V high voltage startup cell • Supports universal AC input (90 Vrms to 305 Vrms) and DC input (127 V to 431 V) • Enhanced
Total Harmonic Distortion (THD)
correction • Enhanced
Power Factor (PF)
correction • PF > 0.9 and THD < 10% across a wide load range, for AC input up to 277 Vrms • High efficiency and low
Electro-Magnetic Interference (EMI)
, with
Quasi-Resonant Mode, switching in valley n (QRMn)
• No-load standby power as low as < 100 mW and low audible noise, with
Active Burst Mode (ABM)
• Low EMI with switching frequency dithering for constant DC input • Reporting of the input voltage, line frequency, controller temperature, input voltage loss, and error code of last triggered protection, via uni-directional
Universal Asynchronous Receiver Transmitter
communication • Protection features: input over-voltage, input under-voltage, output over-voltage, output short, VCC over- voltage, VCC under-voltage and
Integrated Circuit (IC)
over-temperature protections • UL1310 safety feature: Adaptive CS pin maximum voltage and QRMn minimum valley number limits based on estimated input voltage, to prevent excessive output power at higher input voltage • Digitally configurable parameters: maximum switching frequency, ABM burst frequency, protection threshold and reaction (auto-restart/latch), etc.
