Flyback transformer optimised for industrial applications

TT Electronics has introduced the HM210-05K060LFTR flyback transformer designed for use with Avago's ACPL-32JT/302J IGBT chipset. With its high level of isolation the transformer is optimized for use in demanding industrial motor control and inverter applications. The transformer offers a higher saturation current capability and a lower leakage inductance performance, making it ideal for high efficiency DC-DC applications where size is critical, and to assure the performance and reliability levels that industrial applications demand. In designing the transformer, the company took a holistic approach, considering many aspects in order to produce a product that is perfectly suited to Avago’s ACPL-302J, 2.5A gate drive optocoupler with integrated flyback controller, for isolated DC-DC converter applications. The transformer has a wide operating temperature of -40C to +155C, the latter figure contributing to its excellent 5kV isolation voltage capability between primary and secondary windings. Small in size, the flyback transformer measures just 19.5mm x 14.5mm x 16.5mm (HxWxD) and is designed for PCB mounting. It has a primary resistance of 305 milli-ohms. Used in conjunction with Avago’s chipset, the device is suitable for a wide range of industrial applications including inverters, uninterruptible and switch-mode power supplies, automation systems, DC-DC converters, renewable energy inverters, and AC and brushless DC motor drives.
