RIVERSIDE, Calif., October 3, 2024 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions today introduced a new AEC-Q200 compliant, automotive grade, low profile, high creepage isolation transformer. The Bourns® Model HVMA03F4A-LP8S Series flyback transformer is designed to support high power density for greater efficiency in a compact form factor. These capabilities are required in a wide range of applications, including gate drive and high voltage battery management systems (BMS).

This new flyback transformer series expands Bourns’ portfolio of low power, high creepage isolation transformers. This series operates from a typical 12 V supply with an extended input voltage range of 10 to 24 V, and features a new coil mechanical design that helps to increase system performance and safety. These features make the Model HVMA03F4A-LP8S Series ideal for use with Silicon Carbide (SiC), IGBT and Gallium Nitride (GaN) switching elements in automotive, industrial, and energy storage applications.

The Model HVMA03F4A-LP8S Series is constructed with a center-tapped output to generate a ±5 V supply to aid in biasing gate drive turn on and off circuitry. This new series is AEC-Q200 compliant and uses a basic insulation layer that complies with the IEC 60664-1 standard with a working voltage up to 800 VDC. It also features an 8 mm creepage and 2 mm clearance with a Hi-Pot isolation voltage up to 2750 VAC with an extended operating temperature range of -40 to +125 °C.

Available now, the Bourns® Model HVMA03F4A-LP8S Series is RoHS* compliant.
