40-V isolated comparator-based power supply reference design


This reference design demonstrates a cost focused approach of an isolated power supplies with low current capability. The design consists of three designs of three different topologies. All three design options are based on a high voltage comparator TLV1805-Q1 which works as a free-running oscillator and a driver. All three are unregulated: and the ouptut voltage directly depends on the input voltage.
