XDPL8219 Description
AC Input voltage Output VCC ZCD GD HV XDPL8219 CS GND UART FB CoolMOS™ Feedback Circuit Figure 1 Note: Typical Application for XDPL8219 The SSR CV output in Figure 1 should not be used to directly drive the LEDs. For LED lighting application, it should be converted to constant current output by a second-stage DC-DC switching or linear regulator.
XDPL8219 Key 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
- 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
- Protection features: input over-voltage, input under-voltage, output over-voltage, output short, VCC over
XDPL8219 Applications
- Front-stage PFC converter of the Electronic Control Gear for LED luminaires
