Description
This user manual describes the operation of the SSL5511DB1399 demo board featuringthe SSL LED driver SSL5511T in a 35 W isolated application for universal mains.The SSL5511DB1399 demo board is designed for 50 V at a 700 mA LED string load.The single layer PCB with dimensions 110 mm 50 mm 30 mm is intended for fixturesused in SSL applications.The SSL5511DB1399 demo board provides a simple and effective solution for a universalmains application. It includes a high Power Factor (PF), high efficiency, and a low TotalHarmonic Distortion (THD).The topology uses a single stage flyback converter without Power Factor Correction(PFC) pre-stage.
Features
- SSL5511T LED driver
- Single stage flyback converter without PFC pre-stage
- Analog (0 V to 10 V) dimming interface or PWM dimming
- High efficiencies maintained for 50 % and 25 % loads
- Open LED string protection
- Short circuit LED string protection
- OverCurrent Protection (OCP)
- OverTemperature Protection (OTP)
- Power factor > 0.95
- THD < 10 % for 120 V (AC) to 230 V (AC)
- Efficiency ranging from 88 % to 90 % across the universal mains 90 V to 305 V (AC)
