The working principle of the R-78B12-1.0 can be divided into two stages. The first stage is a synchronous rectification phase, and the second is a linear regulation phase. The synchronous rectification phase relies on two MOSFETs, one on the high side and one on the low side. In this phase, the MOSFETs switch alternately, turning on and off in response to the input voltage. This is done to reduce power loss and increase efficiency. The linear regulation phase takes place after the rectification phase and is used to convert the incoming voltage to the desired output voltage.

The R-78B12-1.0 is a versatile DC-DC converter with a wide range of features and a robust design. Its wide input voltage range, high efficiency, and wide temperature range make it suitable for use in a variety of applications. Its rugged and flexible design make it ideal for automotive, medical, industrial, and commercial applications. Additionally, the device also offers short-circuit protection, over-temperature protection, reverse-voltage protection, and soft-start options.
