Miniature Automotive Push/Pull Transformer PMT9085 Series

Pulse, a YAGEO Company’s, automotive-grade isolation push/pull transformer with its innovative core and bobbin assembly, delivers reinforced insulation with 6.4 mm of creepage distance in a compact 10.4 mm × 9.0 mm × 6.4 mm max package size. This makes it suitable for applications requiring safety compliance for with a working voltage of up to 300 V_RMS/reinforced (600 V_RMS/basic insulation). 3,000 V_RMS hipot isolation is achieved with the enhanced separation of the high-voltage side pins from the core and low-voltage side pins. Designed to work with a wide range of push/pull drivers as parts of a cost-effective open-loop circuit for delivering up to 2 W of isolated power in many automotive applications, the PMT9085 series comes with a range of turns ratios, from 1:1 to 1:5, to deliver the required output voltage from a regulated voltage source. A negative voltage for robust SiC/GaN switch-off can be generated from the single winding output using the bootstrap technique.
