SY5800A Evaluation Report Single-stage, flyback, PFC-capable LED driver

sy5800a Evaluation report QQ 2892715427

A single-stage, Flyback, PFC-enabled primary-side control drive IC for LED lighting applications

The sy5800a is a single-stage, flyback, PFC-capable led driver chip for LED lighting.

The system works in quasi-resonant mode to achieve high efficiency and low EMI applications.

The primary edge control does not use any secondary feedback signals and circuitry, thereby reducing the number of BOM devices and reducing the overall cost of the program.

Application T8 lamp, PAR lamp, bulb light, flood light, lawn lamp and so on.

Quick Start Guide

1. The input of the power supply is provided by L and N.

2. The output of the power supply is connected to the load by led+ and led-.

3. The input voltage range is: 90v-264v.

4. When the input voltage is started, the output current value is measured.
