- Low profile, surface mount flyback transformer
- Developed for use with the Maxim MAX17497A/MAX17497B AC-DC and DC-DC Peak-Current-Mode Converters for wide input-voltage nonisolated power supplies to supply multiple output rails for smart meters, industrial control and similar applications.
- Universal input; multiple outputs
- Meets functional insulation class for use in nonisolated applications.
