DC DC converters are important components of electrical systems. They are used to convert direct current from one voltage level to another. Among them, TDR 2-1213SM is an efficient, reliable and compact DC DC converter, suitable for a wide variety of industrial, commercial and residential applications. This article discusses the application field and working principle of TDR 2-1213SM.

The TDR 2-1213SM is a low-cost miniature buck converter with a wide input voltage range and high efficiency. It can provide output voltage from 0 to 13.5 V and input voltage from 3V to 24V. In addition, the TDR 2-1213SM is EMI-compliant and can work under harsh environmental conditions. Because of these features, it is especially suitable for applications that require a low-cost, reliable and space-saving solution, such as telecommunication systems, industrial and medical equipment, household appliances, automotive electronics, smart grid system and more.

The working principle of TDR 2-1213SM is based on a traditional buck converter circuit. It contains some basic components such as power transistor, control IC, inductor, diode and other passive components to construct the circuit. The pulse width modulation technique is used to control the power transistor. The pulse width modulation (PWM) signal is controlled by circuit control IC, and the duty cycle of the PWM signal is changed according to the requirements, so as to control the voltage or current output of power transistor. When the PWM signal is "on" (high), the power transistor conducts and the output of the circuit is the input voltage multiplied by the duty cycle. When the PWM signal is "off", the power transistor will turn off and the inductor will release the stored energy, which is the output voltage.

In addition to providing the output voltage according to the requirements, the TDR 2-1213SM also has various protection functions, such as over-voltage, over-current, over-temperature protection, etc., to ensure the safe operation of the circuit. It also has excellent EMI performance to meet various industrial standards.

In summary, the TDR 2-1213SM is an efficient, reliable and compact DC DC converter, suitable for a wide variety of industrial, commercial and residential applications. Its wide range of features make it an ideal solution for those applications that require a low-cost, reliable and space-saving solution. The working principle of TDR 2-1213SM is based on a traditional buck converter circuit, and it also has various protection functions to ensure the safe operation of the circuit.
