ZD2020-AE Isolated buck transformer

for STMicroelectronics STEVAL-6986YT2DL

The ZD2020-BE iso-buck boost converter transformer, purpose-built for the STEVAL-6986YT2DL reference design, is optimized for systems using the A6986I from STMicroelectronics. This robust component handles input voltages from 5 V to 24 V, delivering dual isolated outputs tailored specifically for SiC MOSFET gate drivers, with typical output voltages of 20 V and -5 V. Rated for 1500 Vrms isolation, the transformer includes standard functional insulation, with optional basic or reinforced insulation available to meet specific application needs. Its AEC-Q200 qualification underscores its reliability and suitability for demanding automotive and industrial environments. For GaN gate drivers, the ZE2774-BE is the preferred choice.

Designed for an input voltage range of 5 to 24 V with dual isolated outputs
Suitable for isolated IGBT/SiC gate driver, On-board charger for HEV/EV, and industrial application.
Functional insulation only. Basic or reinforced versions can be made available per request.
AEC-Q200 qualified
