Power Integrations SIT1217I and SIT1253I DC/DC transformers
The SIT1217I and SIT1253I are DC/DC transformers that deliver a secondary-side voltage of 25 V to support SCALE-iDriver gate driver ICs
The SIT1217I and SIT1253I are DC/DC transformers that deliver a secondary-side voltage of 25 V to support SCALE-iDriver gate driver ICs.
Both are UL and VDE approved, simplifying safety certification and reducing time-to-market.
The innovative transformer structure provides excellent reliability and strong isolation combined with low coupling capacitance.
The high isolation capability is achieved without the need for mold compound.
Different winding ratios support a primary-side supply voltage of either 5 V (SIT1253I) or 15 V (SIT1217I).
