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)
  • Minimal changes required in application for a non-dimmable design using theSSL5101T
  • Compliant with IEC61000-3-2 harmonics standard
  • Compliant with FCC15 EMC standard

Typical applications

  • Smart Dimmable driver modules for LED lighting,Smart Dimmable retrofit LED lamps
