DC-DC converters are a type of power conversion technology that can convert a fixed DC voltage into another DC voltage of a different magnitude. The TDR 3-1212SM is an example of a DC-DC converter, specifically a stepping module. It is designed to provide step-up and step-down voltage conversion within a wide range of input voltage from 1.35V to 80V and output voltage from 0.9V to 75V.

Application Field

The TDR 3-1212SM DC-DC converter offers a high level of performance for both input and output current control. The device is suitable for use in applications ranging from mobile device USB charger, cellular baseband power supply, automotive Ethernet, and other low-power embedded designs. It is ideal for applications that require a high level of accuracy and precision, such as communications, automotive systems, medical, and battery-powered devices.

Working Principle

The TDR 3-1212SM DC-DC converter works by using a switching voltage regulator circuit that converts an input voltage from 1.35 to 80V to a desired output voltage of 0.9 to 75V. The output voltage is regulated by controlling the frequency of the switching regulator. The frequency is varied by adjusting the frequency reference and set up the adjustable range of the frequency reference, then input the external PPL (pulse-position-lock) signal. The regulator is able to adjust the output voltage according to the input external PPL signal.

The circuit is capable of providing a high level of power conversion efficiency, and is able to handle up to 2A of output current. It is also designed with a power good output pin, allowing for voltage monitoring and detection. The TDR 3-1212SM is also designed with a temperature monitoring system, allowing it to detect any changes in temperature and adjust the regulator accordingly.

Conclusion

The TDR 3-1212SM DC-DC converter is an ideal device for applications requiring a high level of accuracy and precision for voltage conversion, such as communications, automotive systems, medical, and battery-powered devices. The device\'s switch voltage regulator circuit is capable of providing high efficiency and excellent output current control, making it a reliable and suitable choice for many applications.
