Working Principle

The PTH04040WAZT is a non-isolated buck converter. It works by converting a higher DC input voltage into a lower, adjustable output voltage. It does this by using a voltage-regulating switch, usually an insulated-gate bipolar transistor (IGBT), as well as an inductor and a filter capacitor.

The IGBT acts as a switch, switching the inductor on and off at a high frequency in order to create the desired output voltage. The inductor acts as a storage device, storing energy when the IGBT is switched on, and releasing it when the IGBT is switched off. The filter capacitor acts as a smoothing element, reducing the output ripple voltage, as well as providing energy storage.

The output voltage of the PTH04040WAZT converter is adjustable using a certain voltage level or a DAC to the External Voltage set pin. The output voltage is controlled by the Duty Cycle, which is set by the on time of the IGBT switch. The Duty Cycle is usually set using pulse width modulation (PWM), which is generated by an internal oscillator.

Conclusion

The PTH04040WAZT is a non-isolated DC-DC converter that can be used to convert a DC input voltage into a preset output voltage. It can be used in a variety of applications, including industrial, medical, and automotive applications. The converter works by using an IGBT as a switch, an inductor to store energy, and a filter capacitor to reduce output ripple and provide energy storage. The output voltage is adjustable using a certain voltage level or a DAC, and is controlled by the Duty Cycle which is set using a PWM signal generated by an internal oscillator.
