DER-515 - 12 W Non-Dimmable Non-Isolated LED Driver
资料介绍

This engineering report describesa non-dimmable, non-isolated buck-boostLED driver designed to drive a nominal LED voltage string of 75V at 160mA from a wide input voltage range of 90VACto 308VAC. The LED driver utilizes the LYT5226Dfrom the LYTSwitch-5family of devices.

The LYTswitch-5is a family of devices which are designed especially for non-dimmablewide range ac inputLED drivers with a single stage PFC function and accurate LED current control.

The DER-515provides a single 12 W constant current output.The key design goals were high efficiency, low THD, low componentcount and low height profile.This design is intended for tubeLED applications.

The document contains the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout,design spreadsheet and performancedata.
