DC-DC converters are devices used to convert direct current (DC) power from one voltage level to another, and are used in a wide variety of applications. To put it simply, DC-DC converters are a type of switch mode power supply (SMPS) that convert direct current (DC) electricity into alternating current (AC). The PDS2-S5-S3-M-TR is a type of DC-DC converter used in various applications. In this article, we will look at the application field and working principle of the PDS2-S5-S3-M-TR.

Application Field

The PDS2-S5-S3-M-TR converter is widely used in telecommunications, computers and consumer electronics. It is well-suited for high density applications, such as point-of-load (POL) and distributed power systems, and offers excellent power and performance. The converter is also used in other applications such as data storage, small form factor machines, robotics and motion control.

The key features of the PDS2-S5-S3-M-TR converter include a wide input voltage range of 3VDC to 5VDC, a wide output voltage range of 2.5VDC to 3.3VDC, and a maximum switching frequency of 200kHz. It has a simple, compact design and a high power density of 1.2W/mm². It also provides excellent EMI performance, with reduced line-noise, and a reduced peak-to-peak ripple. In addition, the PDS2-S5-S3-M-TR converter has a reliable overvoltage protection circuit, and is RoHS compliant.

Working Principle

The PDS2-S5-S3-M-TR converter is a non-isolated buck DC-DC converter, which means it does not provide electrical isolation between the input and output. It is composed of several components – an input capacitor, an inductor, an output capacitor, an output diode, and a PWM controller. The PWM controller generates a pulse-width-modulated (PWM) signal, which is used to control the on/off switching of a power switch, which in turn controls the power flow from the input to the output. The power switch is activated whenever the PWM signal is high, and deactivated when the PWM signal is low. When the power switch is activated, the energy stored in the inductor is transferred to the output capacitor, which provides the output voltage.

The PDS2-S5-S3-M-TR converter works by sequentially switching the power and energy between the input and the output. When the power switch is activated, the energy from the input is stored in the inductor, and when the power switch is deactivated, the energy stored in the inductor is transferred to the output capacitor. By controlling the on/off switching of the power switch, the output voltage is regulated.

The PDS2-S5-S3-M-TR converter also provides protection against overvoltage by monitoring the output voltage and limiting the amount of energy transferred from the inductor to the output capacitor when the voltage exceeds the specified limit. This protects the converter from being damaged by overvoltage, and also helps maintain the stability of the output voltage.

Conclusion

DC-DC converters are a type of switch mode power supply (SMPS) used to convert direct current (DC) electricity into alternating current (AC), and the PDS2-S5-S3-M-TR is a type of DC-DC converter used in various applications. It is used for high density applications such as point-of-load (POL) and distributed power systems, as well as in applications like data storage, small form factor machines, robotics and motion control. It works by sequentially switching the power and energy between the input and the output, and provides protection against overvoltage by monitoring the output voltage and limiting the amount of energy transferred from the inductor to the output capacitor when the voltage exceeds the specified limit.
