RDK-378: 82mA @ 85V Max, 190 ~ 265VAC in

Summary

This document describes a cost-effective power supply utilizing the LYTSwitch™-0 family (LYT0006D) in a highly compact buck topology.

This power supply operates over an input voltage range of 190 VAC to 265 VAC. The DC bus voltage is high enough to support an 85 V output when using a buck topology - in a buck converter the output voltage must always be lower than the input voltage. The output voltage is also limited by the maximum duty cycle of the LYTSwitch-0 (which also requires the input voltage to be larger than the output voltage).

The reference design is not limited for retrofit lamp application; the design layout can be easily modified to fit in LED tube or ballast applications.
