PTB48520WAZ

DC-DC Converters

DC-DC converters are electrical devices used to convert one type of DC voltage or current to another. DC-DC converters are used in a variety of applications, from powering small electronic devices to providing reliable power for industrial machinery. In this article, we will take a look at the PTB48520WAZ application field and working principle.

Application Field

The PTB48520WAZ is a high-efficiency point-of-load (POL) DC-DC converter designed for high-current, low-voltage applications. It is suitable for powering microprocessors, FPGAs, digital signal processors, and other low-voltage electronic components. It offers up to 18A continuous output current and extremely low output voltage ripple for superior performance. The PTB48520WAZ has an adjustable output voltage range of 0.8V to 1.8V and is capable of delivering up to 85W of power.

Working Principle

The PTB48520WAZ works by converting an input voltage of up to 32V directly into an adjustable output voltage of 0.8V to 1.8V. The DC-DC converter works by regulating the current flow between the input and output terminals. This is done by using two main components: an inductor and a switch. The inductor stores energy in a magnetic field and the switch is used to control the flow of energy.

When the switch is closed, the inductor will store energy in its magnetic field and also convert some of the current from the input voltage into the output voltage. When the switch is opened, the energy from the inductor is released, resulting in the output voltage being lower than the input voltage. This process is repeated continuously until the desired output voltage is achieved.

Conclusion

The PTB48520WAZ is a high-efficiency point-of-load DC-DC converter designed for low-voltage applications. It has an adjustable output voltage range of 0.8V to 1.8V and is capable of delivering up to 85W of power. It works by using an inductor and a switch to regulate the current flow between the input and output terminals. This allows the PTB48520WAZ to efficiently convert one type of DC voltage or current to another.
