Description

This reference design demonstrates a method for designers to achieve high-voltage signals that can be used for flame detection using discrete components. The reference design is built with low BOM-cost and small solution size in mind. By using push-pull converter topology, it is possible to achieve a wide input range and low start-up time.

Features
  • Universal input range of 10 to 36V
  • 120V, 60Hz output with 4% THD
  • 56ms startup time at 10V
  • 5% output accuracy
  • Output power up to 1W
  • Low footprint and BOM cost
