Application Field

The RPM40-1212SG DC-DC converter is designed for a wide variety of applications like automotive, industrial, communication equipment, portable electronics and toys. This converter is typically placed in automotive applications that require 12Vdc conversion to lower outputs for the powering of loads such as radios, CD and DVD players. It is also used in industrial applications such as central office power rectification and telecommunications equipment for power supply for the auxiliary converter. This converter also finds its use in aerospace, railway and other heavy industrial applications.

Working Principle

The RPM40-1212SG converter is a voltage regulator device that converts an unregulated DC voltage from one level to another decreased DC voltage level. It is a switch-mode regulator, which means that it uses a pulse-width-modulated (PWM) signal to adjust the voltage level. The PWM signal is generated by the internal integrated circuit (IC). The input voltage is compared with the output voltage, and the difference is the error. The error then passes through the error amplifier, which generates the PWM signal. This PWM signal is then used to adjust the output voltage. The feedback resistor reduces the voltage difference between the output voltage and the reference voltage, thereby resulting in a stable output voltage.

Conclusion

The RPM40-1212SG DC-DC converter offers excellent noise performance and low ripple. It operates in a wide input voltage range and offers over-voltage protection. This converter is designed for automotive and industrial applications, where the need to convert an unregulated 12Vdc level to a lower DC voltage is very important. It is also very useful in isolated and noisy environments, where an efficient and stable voltage regulator is needed. The converter operates according to the pulse-width-modulated (PWM) switching technique and has a minimum and maximum operating temperature range.
