ZD2024-AE

Isolated Buck Transformer for STMicroelectronics STEVAL-250GANCB

The ZD2024-AE isolated buck transformer has a lower profile than other core/bobbin sets, making it ideal for compact designs. This transformer is optimized for iso-buck converters, leading to more efficient power supplies. It is designed for a 5-12 V input and generates four 12 V / 25 mA output.

Designed for STMicroelectronics’ STEVAL-250GANCB high-efficiency power adapter based on GaN and digital control
Optimized for 12 V isolated-buck auxiliary power supply
2000 Vrms, one minute isolation (hipot) between primary and secondary
AEC-Q200 qualified

Notes

Inductance is for the primary, measured at 500 kHz, 0.1 Vrms, 0 Adc.
DC current that causes the primary inductance to drop 30% from its value without current.
Leakage inductance is for the primary with the secondary windings shorted.
2000 Vrms, one minute isolation (hipot) between primary and secondary windings.

Termination:
