The BD9G341AEFJ uses Rohm’s high voltage 0.6µm BiCDMOS process to achieve a maximum breakdown voltage of 80V – said to be the highest in its non isolated DC/DC converter lineup – and a continuous operating input range of 12 to 76V. In addition, multiple protection circuits are said to minimise heat generation, even during output pin shorts.
The device can supply an output adjustable from 1V to Vcc, with a maximum current of 3A. With a typical operating frequency ranging from 50kHz to 750kHz, the device can be used in temperatures ranging from -40 to 85°C.
Supplied in an 8pin package measuring 4.9 x 6 x 1mm, the part is said to reduce the number of parts required from 17 to 12, simplifying end-product design, BoM costs and development efforts.
