DER-364 - 14 W dimmable, high efficiency (>85%) LED driver

The document describes an isolated high power factor (PF), thyristor-dimmable LED driver that can provide a rated voltage of 41 V and a rated current of 350 to an LED string within an input voltage range of 90 VAC to 132 VAC. mA driver. This LED driver uses the LYT4313E device in the LYTSwitch series IC. The topology used is a single-stage, buck topology with power factor correction, which provides high efficiency, high power factor, high power factor, low THD and low component count. LYTSwitch IC can also provide various complex protection functions, including automatic restart under loop open or output short-circuit conditions. This device can be used to achieve high power factor and low THD. Input overvoltage shutdown provides enhanced immunity to input faults and surges, and accurate hysteretic thermal shutdown ensures that average PCB temperatures remain within safe limits under all conditions. The document includes LED driver specifications, circuit schematics, PCB design drawings, bill of materials, transformer specification files and typical performance characteristics.
