TMR 1-1212SM Datasheet/PDFThe TMR 1-1212SM DC-DC Converter is a series of small, advanced bidirectional DC-DC converters, capable of providing a conversion efficiency of up to 95%. This design is perfect for applications where a small and reliable power source is needed in a low space envelope. The TMR 1-1212SM is equipped with a PWM-driven topology and features a low-side MOSFET power switch to reduce switching losses.
The primary application field of the TMR 1-1212SM is in the area of industrial automation, motors, and renewable energy applications. It has been used to control industrial robots, power pumps, fans, and drives in a wide range of applications. For example, in the machine tool industry it is widely used to control electrical power and the movement of automated machines. Furthermore, it is also applicable for the control of variable speed drives in renewable energy such as solar and wind power systems.
The working principle of the TMR 1-1212SM can be explained as follows: The circuit consists of a MOSFET power switch, a Darlington switching transistor, and a high-frequency proprietary control topology. A PWM signal is fed into the high-frequency control topology, which pulses the MOSFET to move the load voltage to the desired output voltage. This MOSFET regulated voltage is then rectified by the Darlington switching transistor and conditioned by an output inductor. The output inductor isolates the capacitive load from the power switch node and eliminates electromagnetic interference (EMI) generated from the power source.
The TMR 1-1212SM also includes a variety of built-in protection features to ensure safe and reliable operation. This includes over-voltage, over-current, and over-temperature protection, as well as short circuit protection and soft-start functionality. This effectively reduces the risk of accidental damage due to improper operation or excessive loading of the power source.
In conclusion, the TMR 1-1212SM provides a highly efficient, compact, and reliable DC-DC conversion solution for applications in the industrial automation, motors, and renewable energy sectors. Its advanced topology and wide range of protection features make it an ideal choice for these applications.
