DC-DC converters, which can be used to convert different levels of voltage, are widely applied in various electrical and electronic domains. One of the main type of DC-DC converters is PT6122N, which is capable of converting the input voltage into the required level or converting the output voltage to the needed level or both. This application report introduces the principles and fields of application for the PT6122N.

Functional Characteristics of PT6122N

The primary function of the PT6122N is its ability to convert the input voltage to the desired voltage. Generally speaking, it converts the input voltage of VIN to the actual output voltage VOUT, producing a working frequency of up to 75MHz. By external components, the power level of the output can be regulated to meet different requirements.

In addition, the PT6122N also offers short circuit protection, over current protection, and temperature protection for all different levels. The output power level can be manipulated by pulse width modulation, allowing it to conveniently satisfy system needs. This converter is also designed with an adjustable output voltage, enabling the system to adjust and switch operations flexibly.

Typical Application Scenario of PT6122N

The PT6122N is mainly applied in mobile phone, notebook, as well as tablet applications as a power management unit. It can effectively function to reduce the overall power consumption. Furthermore, the converter is also used in other emerging electronic products such as LED lighting systems and electric vehicle management systems.

Multiple types of power converters can be used to convert the input source to the specific output voltage and currents. In this regard, the PT6122N provides advantages of good stability and wide working range such that it can be used in different scenarios. This demands the voltage and current range must be negotiated within the safety level, while providing sufficient voltage and current levels to satisfy the operating needs.

Structure and Working Principle of PT6122N

The working principle of the PT6122N is based on Pulse Width Modulation (PWM). By using a switch mode principle, the PT6122N can reduce the voltage of the power source using a fixed OFF period and a short ON period. The output voltage is created by prolonging the ON period. The PWM forms a signal with a proportionally corresponding pulse period to the inputted voltage.

The structure of the PT6122N is based on the rotating frequency. It can be composed of a primary circuit and secondary circuit together with several switching elements. The rotating cycle is controlled by a self-oscillating voltage regulator. According to autonomous oscillation, the PWM transformer can regulate the voltage output.

Conclusion

The PT6122N is a self-oscillating converter withhigh reliability and stability. It works based on the principle of pulse-width modulation and can be used in industries like mobile devices, LED lights, and electric vehicle management systems.
