DC-DC Converters: SUS32405B-G Application Field and Working Principle

DC-DC converters are devices which convert direct current (DC) from one voltage level to another. They are used in numerous applications involving power management, renewable energy applications and industrial control systems. The SUS32405B-G converter is a switch-mode DC-DC converter that offers a regulated output voltage, no-load operation and a wide range of operating temperatures.

Application Fields of SUS32405B-G Converter

The SUS32405B-G converter is highly versatile and offers many applications. It is suitable for use with a variety of power sources such as NiCad batteries, as well as more permanent sources such as solar energy or wind energy. In addition, it is also suitable for industrial applications, such as robotic arms, as it can provide the output voltage level needed to power these types of machines. In automotive applications, it is ideal for airbags and seatbelt pretensioners. It is also suitable for aircraft applications because it can provide the desired output voltage levels with high efficiency and minimal noise. In addition, it is suitable for space applications as the device is lightweight and has a low creepage and clearance profile.

Working Principles of SUS32405B-G Converter

The SUS32405B-G converter uses a buck-boost topology to convert a high input voltage to a lower output voltage. The input voltage is fed through a transformer, which is then rectified and filtered to create a DC input voltage. This DC voltage is then fed to the control circuit, which uses pulse width modulation (PWM) to adjust the output voltage. The PWM signals control a pair of power switches, which are connected in series. The switches are connected to a coil, which creates a magnetic field when the switches are activated. This magnetic field is then coupled with the output inductor, which allows for a smooth transfer of power between the input and output stages.The output voltage of the SUS32405B-G is stacked onto a boost capacitor and fed to the output which has a voltage range of 3.75 – 36 volts. The output voltage is regulated by an onboard control switch which senses the output voltage and adjusts the duty cycle of the power switches to maintain the desired voltage level.

Conclusion

The SUS32405B-G converter is a high-efficiency DC-DC converter that is well suited for a variety of applications. It provides a regulated output voltage, no-load operation and a wide range of operating temperatures. The SUS32405B-G operates on a buck-boost topology which is controlled using a combination of PWM and power switches. This allows for a smooth power transfer between input and output stages. The output voltage range is from 3.75 - 36 volts and is regulated by an onboard control switch.
