This document is a user guide released by Fairchild Semiconductor Corporation in 2012, which introduces the features and characteristics of the FEB-L026 evaluation board and the FL7732 primary-side regulator.
The document provides a comprehensive overview of the FEB-L026 Evaluation Board, which utilizes the FL7732 single-stage controller to create a cost-effective solution for universal line voltage LED ballasting. The board is designed to operate with an input voltage range of 90V RMS to 265VRMS and delivers a constant current output.
| Input Voltage Range | 90V RMS – 265VRMS |
|---|---|
| Nominal Output Current | 700mA |
| Maximum Output Voltage | 28V MAX |
| Operating Frequency Control | Proportionally changed by output voltage |
The evaluation board achieves an efficiency of 86.45% when operating at a 90V AC line input voltage.
The board provides a constant current of 700mA at a maximum output voltage of 28V.
The device operates on universal line voltage ranging from 90V RMS to 265VRMS.
The board measures 79mm in length, 30mm in width, and 20mm in height.
