V48C5C50B3

DC-DC converters are electrical components which are used to convert direct current from one voltage level to another. Generally, they can be found in a range of electronic devices, such as computers, domestic appliances and industrial machinery. V48C5C50B3 is a DC-DC converter specially designed for automotive applications. It can accept inputs from 12 and 24V battery sources and convert them into adjustable outputs voltage of approximately 5.5V, adjustable within 0.5 percent accuracy.

Application Field

V48C5C50B3 DC-DC converters are widely applied in automotive electronics for high performance DC-DC conversion. It is conventionally mounted on PC-board and is capable of providing a 5V regulated voltage supply for high current automotive applications. This converter is also suitable for use in high power applications in telecom systems, medical instrumentation, as well as industrial control system. It is suitable for use in harsh environments.

Working Principle

V48C5C50B3 DC-DC converters use a buck-boost concept to convert input from a 12 or 24 volt battery to a 5.5 volt output. All of the components of this device are fully integrated and optimised onto a single highly reliable circuit board. At the input end, the input voltage is sampled by sensing resistor R1 and is compared to the internal 5.5V reference voltage.

Based on the comparison result, the control circuitry determines whether to increase or decrease the output voltage. If the input voltage is lower than the reference voltage, the integrated field-effect transistor (FET) will be turned on and the buck regulator will start operating, hence increasing the output voltage.

When the input voltage is higher than the reference voltage, the integrated FET will be turned off and the integrated boost regulator will be turned on, hence decreasing the output voltage. The integrated controller also limits the current, keeping it within safe recommended levels so as to ensure excellent reliability of the V48C5C50B3 DC-DC converter.

Conclusion

V48C5C50B3 DC-DC converters are widely used for efficient DC-DC conversion in automotive applications. They are highly integrated, reliable and suitable for usage in harsh environments, such as in telecom, medical and industrial systems. The working principle of the V48C5C50B3 DC-DC converter involves sensing input voltage, comparing it to an internal reference voltage and then determining whether to increase or decrease the output voltage.
