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 90 VAC to 132 VAC. The DC bus voltage is high enough to support a 38 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.
