TEL 5-1222

DC/DC converters are vital components in electronic applications. They convert DC voltage from one level to another. The TEL 5-1222 is a very versatile DC/DC converter designed for applications requiring input voltages. It can provide a constant DC output voltage up to 12V from input sources as low as 5V ¹.

The TEL 5-1222 is suitable for a wide range of applications such as in industrial settings, communications equipment, light sources, and numerous other electronic devices. The 5-1222 has a very efficient design and offers a high level of adaptability. It features multiple circuit protection including under voltage, over voltage, over temperature, and current limiting.

The TEL 5-1222 DC/DC converter offers outstanding noise immunity and safety protections. Its operating efficiency is up to 90%, and the switch frequency range is 250kHz. The converter comes with a wide input voltage range of 4.5V to 5.5V and provides a constant output up to 12V. The output voltage can be adjusted as much as from 6V to 12V, depending on the application.

The working principle of the TEL 5-1222 is simple. First, the input voltage is rectified and filtered to prevent high-frequency noise from entering the system. This is followed by a step-down transformer that reduces the voltage to a lower level. The voltage is then regulated by control circuits, such as a pulse width modulator (PWM) or pulse frequency modulator (PFM).

Finally, a power switch and a storage capacitor are used to supply the DC output voltage. The power switch alternates between on and off states, and the storage capacitor ensures that the output voltage is constant and independent of changes in the input voltage. This means that when the input voltage changes, the power switch is used to adjust the output voltage, limiting the changes in the output voltage.

The TEL 5-1222 DC/DC converter is a reliable, efficient, and efficient solution for applications requiring up to a 12V output from a 5V supply. It is cost-effective, and its wide range of application fields makes it a great choice for many different electronics projects.
