DC DC Converters: V28C24H100BS application field and working principle

DC-DC converters, broadly defined, are electric circuits which convert a fixed Direct Current (DC) electrical voltage into a different, adjustable, or alternating DC voltage. DC-DC converters can range from merely adopting a voltage to sophisticated and adjustable power supplies. Commonly used V28C24H100BS converters are a type of Non Isolated DC-DC converter relying on FETs. This article discusses the application field and working principle of the V28C24H100BS DC-DC converter. The V28C24H100BS converter is an 8-pin, dual channel, Non Isolated DC-DC converter. The device is designed for step-down applications operating on input voltages up to 24V. It features adjustable output current range up to 100mA and low standby current consumption.

Application Field

The V28C24H100BS converter is particularly suited for applications which require high power efficiency, low noise, and excellent power supply control. It is ideal for powering digital components such as ASICs, FPGAs, MCUs. Additionally, the V28C24H100BS converter is used to supply power for LED drive, PLCs, Programmable Logic Controllers, adjustable and precision analog circle, servo motor drivers, and automated testing equipment.

Working Principle

The V28C24H100BS DC-DC converter employs FETs (Field Effect Transistors) as its main elements. The FETs work as switches which selectively allow voltage coming from the power source to pass through to the load. By rapidly and accurately turning the FETs on and off, the converter generates an output that is both adjustable and smooth.The FETs are switched on and off by two control lines (e.g. Error Amplifier Output Voltage and Error Amplifier Output Current). The Error Amplifier Output Voltage is the voltage that sets the reference output voltage of the converter. This voltage is used to control the FET switch on time which in turn controls the output voltage of the converter. Similarly, the Error Amplifier Output Current is used to control the FET switch off time, allowing the converter to regulate the output current.

Conclusion

The V28C24H100BS DC-DC converter is a non-isolated, 8-pin, dual channel converter. It is mainly used to supply power for digital components, LED drive, PLCs, adjustable and precision analog circuits, servo motor drivers, and automated testing equipment. The converter employs FETs as its main elements, which work as switches allowing voltage from a power source to pass to the load. The switching frequency is determined by the Error Amplifier Output Voltage and Error Amplifier Output Current.
