DC DC Converters

DC-DC converters are among the most important components of electronic circuits. The CBS50482R5-F4 is an example of a DC-DC converter providing reliable and efficient power conversion for a variety of applications. This article covers the CBS50482R5-F4\'s fields of application and working principle.

Applications

The CBS50482R5-F4 converter operates on a wide voltage range, from 4.8V to 60V DC. This makes it suitable for a range of applications, including industrial control systems, smart devices, LED lighting, and automation. Furthermore, its high efficiency, together with low standby power draw, makes it suitable for battery-powered applications.

Working Principle

The CBS50482R5-F4 is a variable-voltage DC–DC converter. When a constant voltage input is applied to it, its output is regulated at a value determined by the setting of the voltage adjust trimmer. The device is integrated in a high-current metal-oxide-semiconductor field effect transistor (MOSFET) package. The device includes two power MOSFETs, a control IC, and a 4-terminal trimmer resistor, or adjust trimmer. When an input voltage is applied to the device, current flows into the drain terminal of the power MOSFET. The current is then passed to the gate terminal and maintains the power MOSFET in the ON state. The current then passes through the adjust trimmer and is measured by the internal control IC which maintains the drain current in a steady state. The trimmer setting determines the voltage level of the output. The voltage at the output of the CBS50482R5-F4 can be varied from 4.8V to 60V. The output current is limited by an onboard internal current limit, and the thermal shutdown feature safeguards the device in case of overload.

Conclusion

The CBS50482R5-F4 is an advanced DC-DC converter that boasts a wide range of applications, including industrial control systems, smart devices, LED lighting, and automation. It operates at a wide voltage range, from 4.8V to 60V DC, and converts a constant voltage input into a regulated output voltage. The output voltage is adjustable by the trimmer resistor, and the device features a current limit and thermal shutdown functions to protect it from overload.
