DC DC Converters

DC DC Converters are an important and indispensable part of electrical engineering. DC DC converters are used to convert direct current (DC) power into other forms of electrical energy such as alternating current (AC) or switched mode power supply (SMPS). This type of converters are widely used in electronics, industrial machinery, robotics, aerospace, telecommunications, automotive and medical applications.

The SUS1R52412B DC DC converter from Texas Instruments is an advanced device designed for use in high-end microprocessor-based systems and applications with stringent power quality requirements. This device is a multichannel, high efficiency, dc-dc buck converter, which provides a rapid response to changes in load current.

Application Fields

The SUS1R52412B DC DC converter is designed for a wide range of applications such as:

• Microprocessor-based systems

Working Principle

The working principle of the SUS1R52412B DC DC converter is based on the buck converter topology. In this topology, the output voltage is derived by switching a power semiconductor device between two different voltage levels. The switching is controlled by an internal amplifier which is connected to the converter’s feedback network.

The converter’s feedback monitor continuously samples the output voltage and adjusts the switch ON time accordingly. This ensures that the output voltage remains stable under variable loading conditions. The SUS1R52412B also features a SoftStart circuit which helps in gradually increasing the output voltage from 0 to the final set point.

The SUS1R52412B DC DC converter is also designed to operate in a temperature range of -40°C to +85°C. This ensures that the converter can operate in extreme environmental conditions.
