BR203 Power Supplies - Board Mount

DC-DC converters are an important component of many types of electric energy systems. The BR203 is a type of DC-DC converter often used in the industrial and automotive industries, providing stable, reliable power conversions. This converter is rated for high efficacy, long-term use, and a wide operating temperature range, making it an ideal choice for a variety of applications.

Design and Specifications

The BR203 is a step-down DC-DC converter, meaning that it reduces a higher input DC voltage to a lower one at the output. The converter has a wide input voltage range of 4.5-30 VDC, and an adjustable output voltage range of 0.6-25 VDC. The efficiency of the converter is very high, reaching 93-96% in most cases. The BR203 also features overload, short-circuit and overtemperature protection as well as remote enable/disable capability.

Applications

The BR203 can be used in a variety of applications, due to its wide input and output voltage range, high efficiency and reliable protection features. It is typically used as a primary power converter in industrial and automotive applications, such as for powering LED lights, charging batteries and powering other devices. The BR203 is also used in other fields, such as medical equipment, telecom and wireless communication, and process control.

Working Principle

The BR203 converter uses a Buck converter topology to convert the input voltage to the desired output voltage. A Buck converter consists of an inductor, a diode, a capacitor and an output transistor. When the input voltage is applied to the inductor, the energy is stored. Then the diode allows the energy stored in the inductor to flow to the capacitor which stores the energy. The output transistor then regulates the voltage to the desired level.

The output voltage is regulated by changing the duty cycle of the transistor. By changing the duty cycle of the transistor, higher or lower output voltage can be obtained. The BR203 features a synchronous rectifier which allows for higher efficiency at higher switching frequencies. The high efficiency of the BR203 helps to reduce the power consumption and heat dissipation, making it an ideal choice for many types of applications.

Conclusion

The BR203 is a high-performance step-down DC-DC converter that provides reliable and efficient power conversion for a variety of applications. It has a wide input and output voltage range, high efficiency and reliable protection features. With its high-performance and reliability, it is an ideal choice for many types of applications in the industrial and automotive fields.
