DC/DC Transformer for SCALE-iDriver Gate Driver ICs Providing Reinforced Isolation up to 1200 V

Typical Application Schematic

Data Sheets

Product Details

The innovative transformer “isolated wire-in-wire” structure provides excellent reliability and strong isolation combined with low coupling capacitance. The high isolation capability is achieved without the need for mold compound. SIT12xxI transformers are UL and VDE approved, simplifying safety certification and reducing time-to-market.

The SIT12xxI is a DC/DC transformer that delivers a secondary-side voltage of 25 V to support SCALE-iDriver gate driver ICs. SIT12xxI transformers are available with different winding ratios to accommodate a primary-side supply voltage of either 5 V or 15 V.
