DC DC converters are power converters which allow for the conversion of a DC voltage in one range to a DC voltage in a different range. One such converter is the CBS504803-F5, a synchronous buck converter designed for use in high current applications. The CBS504803-F5 offers a 4A output current, and operates from inputs in voltages from 4.5V to 28V. It offers adjustable output voltages from 0.6V to the input voltage.

The CBS504803-F5’s main application field is the high current supply for FPGAs. FPGAs are integrated circuits that are highly configurable to suit a wide range of applications. Because of their high configurability, they require both high input voltage and high currents in order to power them. The CBS504803-F5 is designed to provide just such a-high current supply at an adjustable output voltage.

The CBS504803-F5 works on the principle of synchronous buck conversion. Synchronous buck conversion is the process of converting a higher voltage DC, which is applied to the input of the converter, into a lower voltage DC at the output. The power conversion is based on the switching action of two transistors; one acts as a switch to allow current to flow, while the other acts as a current mirror, to ensure that the desired current is efficiently transferred from the input to the output.

Once the transistors have been activated using an internal oscillator, a linear regulator is used to control the output voltage. This is accomplished by a feedback signal from the output, which is compared to an external voltage reference signal. The error is then used to adjust the amount of current flowing through the transistors, and hence, the output voltage.

The other main component of the CBS504803-F5 is its built-in low dropout linear regulator. This regulator is used to minimize the amount of energy wasted as heat, and limits the input voltage to the required level. The regulator is also designed to adjust the switching frequency of the transistors to the appropriate levels, to ensure that the correct output voltage is maintained.

The CBS504803-F5 is a synchronous buck converter that is designed to provide high current supply to FPGAs, in a range of voltages from 4.5V to 28V. It is based on the principles of synchronous buck conversion, along with a built-in low dropout linear regulator, that maintains the desired output voltage. This makes the CBS504803-F5 an ideal power supply for high current FPGA applications.
