No-Opto Flyback Transformer

for MAXIM MAX17690

The ZB1313 flyback transformer is designed to work with the MAX17690 60 V, no-opto isolated flyback controller from Maxim. It has no auxiliary winding and offers the greatest efficiency, lowest cost, and smallest size for synchronous isolated DC-DC power converters. The ZB1313 operates with an 18 – 38 V input voltage range and generates an output at 24 V / 0.7 A, with a peak efficiency of up to 90.6% at full load. The part has a maximum height of just 7.4 mm, significantly lower than other parts recommended for the same chipset.

Notes

Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
Minimum inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 5 Adc.
Leakage inductance is for the primary winding with the secondary windings shorted.
Turns ratios are with the primary and secondary windings connected in parallel.
1500 Vrms, one minute isolation (hipot) between primary and secondary.
