Flyback Transformer for Maxim MAX17497A/B
Peak-Current-Mode Converters
• 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.
• 1000 Vrms isolation, one minute from primary to secondary

1. When ordering, please specify packaging code:
CR8076-ALD
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (200 parts per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.
2. Inductance is for the primary, measured at 250 kHz, 0.1 Vrms.
3. Isolation is from primary to secondary, tested for one minute.
4. Operating temperature range –40°C to +85°C.
5. Electrical specifications at 25°C.
