DER-404 - 8 W dimmable, high efficiency, high PF, non-isolated LED driver for A19 lamps

Schematic PCB
DER-405 - 25 W high efficiency (>90%), high power factor (>0.97) non-isolated LED driver for T10 tubes

Schematic PCB
DER-395 - 14.35 W triac dimmable non-isolated LED driver for PAR30 lamps
This document describes a non-isolated, high power factor (PF), high efficiency, triac dimmable LED driver that operates from an input voltage range of 195 VAC to 265 VAC (50 Hz typical). The LED light string provides a driver with a rated voltage of 41 V and a rated current of 350 mA.
The topology used is a single-stage, non-isolated, tapped buck topology, which can meet the high power factor, constant current adjustment and dimming requirements of this design.
This document contains LED driver specifications, circuit schematics, PCB design details, bill of materials, transformer specification files and typical performance characteristics.
