SSL5301DB1233 230 V 36 W LED driver demo board

1. Introduction

This user manual describes the operation of the SSL5301DB1233 36 W isolated flyback

converter driver demo board featuring the SSL5301T. The demo board is designed for

230 V mains phase-cut dimmable applications.

The SSL5301DB1233 demo board is designed for 48 V at a 700 mA LED string load.

The single layer PCB with dimensions 120 mm  50 mm  30 mm is intended for fixtures

used in SSL applications.

The SSL5301DB1233 demo board provides a simple and effective solution for a 230 V

mains application. It includes a high Power Factor (PF), high efficiency, and a low Total

Harmonic Distortion (THD).

The topology uses a single stage flyback converter without Power Factor Correction

(PFC) pre-stage.
