Isolated SMD Transformer for 6-20W DC/DC Converter ——CTTURA/B-6/10T Series、CTTURB-20T SeriesNov 27, 2019      view:

MORNSUN recently launched two automotive grade transformers for 6-20W DCDC converter - CTTURA/B-6/10T series and CTTURB-20T series. The isolation voltage of transformers is up to 1650VDC, owning operating temperature from -40°C to +125°C, and featuring small size and high cost performance. The transformers’ components meet the AEC-Q200 test standards and meet the requirements of the automotive industry for high-reliability and small-dimension power supplies.

The CTTURA/B-6/10T series and CTTURB-20T series can be matched to use with the MORNSUN SCM1101A secondary feedback control IC. The combination facilitates 4:1 wide-voltage input and 6-20W flyback design with multiple protections and superior EMI performance.


It widely is used in electricity, instrumentation, industrial control, communication industry and so on.
