This document is the user guide for FEB-L027 evaluation board, which introduces the usage and performance test of the evaluation board
The document provides a comprehensive reference report for the FEB-L027 Evaluation Board, which is designed as a universal line voltage solution for T8 LED lamps. It utilizes the Fairchild FL7732 Primary Side Regulator (PSR) single-stage controller to achieve power factor correction and constant current control without an input bulk capacitor.
| Input Voltage Range | 90V RMS – 265V RMS |
|---|---|
| Output Current | 500mA constant current |
| Maximum Output Voltage | 35V MAX |
| Operating Frequency | 60Hz / 50Hz |
| Power Factor (90VAC) | 0.999 |
The design uses the FL7732 Primary Side Regulator (PSR) single-stage controller.
No, the design is cost-effective because it does not use an input bulk capacitor.
The controller provides open-LED, short-LED, and over-temperature protections.
