Power-supply transformers complement Scale-iDriver gate-driver IC series
Power Integrations’ range of galvanically isolated transformers provide the correct voltage and power for the company’s Scale-iDriver family of gate drivers. The combination delivers a DC-DC converter solution that does not require additional voltage regulation. SIT12xxI transformer and Scale-iDriver ICs are fully UL and VDE approved.
The new SIT12xxI transformers feature an insulated construction Power Integrations says improves reliability and delivers a high isolation capability combined with low coupling capacitance. Devices suit 600 V and 1200 V two-channel Scale-iDriver gate drivers with 5 V (SIT1253I) or 15 V (SIT1217I) input voltages and 25 V output voltage.
The shrouded transformers weigh 9g and no potting is required, nonetheless they pass tests for extended field life and high resistance to shock and vibration. They meet UL1446, UL61800-5-1, IEC61800-5-1, IEC61558-1 and IEC61558-2-16.
“The Scale-iDriver family of IGBT and SiC-MOSFET driver ICs employs Power Integrations’ FluxLink magneto-inductive bi-directional communications technology to ensure reinforced galvanic isolation between the primary and secondary sides, setting a new standard in isolation integrity and stability,” said Thorsten Schmidt, product marketing manager for gate-driver products at Power Integrations. “By providing a perfectly matched transformer we reduce system development, qualification and certification time and simplify the purchasing process.
“The new design of the transformer construction targets industrial applications, delivering a rugged and lightweight isolated DC-DC solution while minimising common-mode noise coupling,” he said.
SIT12xxI transformers are available now, priced at $4.00 in quantities of 10,000.
Power Integrations is a leader in semiconductor technologies for high-voltage power conversion. The company’s products are key building blocks in the clean-power ecosystem, enabling the generation of renewable energy as well as the efficient transmission and consumption of power in applications ranging from milliwatts to megawatts.
