ZD2250-AE, ZE2432-AE

Flyback Transformers for Texas Instruments LM5185-Q1

Coilcraft ZD2250/ZE2432-AE flyback transformers are designed to work with the LM5185-Q1 100 V_in PSR flyback automotive DC-DC controller from Texas Instruments. These transformers have no auxiliary winding, reducing solution size and cost while achieving greater than 90% efficiency, making them suitablefor use in isolated bias power supplies for IGBT, SiC, and GaN gate drivers.

The ZD2250/ZE2432-AE are AEC qualified, making them ideal for automotive traction inverters, onboard chargers (OBC), EV charging stations, battery management systems (BMS), automotive DC-DC converters and wide range of other automotive and industrial applications.

Optimized to work with the PSR Flyback DC-DC controller LM5185-Q1 from Texas Instruments
Designed to operate with 18 – 60 V (ZD2250) and 9 – 60 V (ZE2432) input at 200 kHz
2000 Vrms one minute isolation (hipot) primary to secondary
AEC-Q200 qualified with max part temp at 165°C

Notes

Inductance is for the primary, measured at 200 kHz, 0.1 Vrms, 0 Adc.
DC current that causes an inductance drop of 30% (typ) from its value without current.
DCR values specified with windings connected in parallel.
Leakage inductance is for the primary winding (connected in parallel) with the secondary windings shorted.
2000 Vrms, isolation (hipot) measured between primary windings (connected in parallel) to secondary windings (connected in parallel).
