DC-DC converters are a type of electronic device used to convert a dc input voltage into a different dc output voltage. They are more efficient and cost effective than linear and unregulated supplies, and offer the user increased flexibility when it comes to configuring complex power systems. The PTH08T261WAD is the latest DC-DC converter from Intersil and it is designed to provide a regulated +5V output from a 6V to 36V dc input.

The PTH08T261WAD is a monolithic integrated circuit based on a buck-boost topology. Its internal switching frequency is adjustable, using an external clock, from 350kHz to 1.5MHz. This enables the user to optimize performance for a variety of operating conditions. It also offers an adjustable soft-start, which allows it to slowly increase its output voltage, eliminating large inrush currents, which can be generated when powered up from a low-voltage point. The PTH08T261WAD also has an integrated over-temperature protection and thermal-shutdown circuitry, providing an extra layer of protection against power supply destruction.

The PTH08T261WAD application field includes many applications such as system power buses, routers, switches, or any other digital system. It can also be used to power applications where there is a need for a high-efficiency, wide-input-voltage voltage regulator. The PTH08T 261WA’s low profile package is ideal for applications that have limited mounting space. The PTH08T 261WA can be used as a standalone voltage regulator or in an automated system to provide a regulated output voltage.

The PTH08T261WAD working principle relies on several stages. First, it receives the input voltage and then it goes through the buck converter, which lowers the DC voltage. The buck-boost converter adjusts the output voltage according to the input voltage and converts the input voltage into a steady DC output voltage. In the boost converter stage, an inductor is used to store a magnetic energy and then it is released to the output. The final output is given by the LDO (low-dropout) regulator, which ensures the output maintains a steady voltage despite minor fluctuations in the input.

The PTH08T261WAD is a powerful DC-DC converter capable of providing a stable +5V supply from a wide input voltage range. Its adjustable soft-start feature eliminates current inrush, its thermal-shutdown protection prevents the device from being damaged by high temperature and its adjustable switching frequency allows users to optimize performance. Overall, this makes the PTH08T261WAD an ideal choice as a wide input voltage regulator in a wide range of applications.
