STR05S2V5

DC-DC Converters are electronic circuits that convert a direct current (DC) voltage from one value to another, usually to provide a source of power at a lower voltage than the input value. STR05S2V5 is a high-performance DC-DC converter which can be used in a variety of applications. The converter is characterized by high efficiency, high power density, and tight regulation.

Operating Principle

The STR05S2V5 is a step-down converter and it derives its power from an unregulated, high input voltage source. It filters out most of the unwanted switching noise and provides a fully regulated low output voltage. The converter features synchronous rectification to achieve high conversion efficiency and a low quiescent current.

The STR05S2V5 utilizes two independent switches which are controlled by a current-mode PWM controller. This ensures that the output voltage remains constant regardless of input voltage variations and the output load. The input voltage is reduced using an inductor, input capacitor and voltage drop schottky diode and the output voltage is regulated by operating the switches in different ratio, thus controlling the duty cycle of the input current. Furthermore, the output voltage is protected against load current surges by employing external MOSFET switches, which are connected in parallel to the main remote switch.

Application Field

The STR05S2V5 is most commonly used in automotive, industrial and consumer electronics applications. More specifically, it can be used in battery powered devices such as portable media players, power banks, Bluetooth wireless devices, IoT sensors, handheld radios and washing machines.

The STR05S2V5 can also be employed in medical and military applications, including medical imaging systems, portable patient equipment and defense systems. It is capable of providing high performance, reliable operation with low power consumption and reliable performance in high environments. The converter is also compliant with the applicable CEC and EMC standards.

Conclusion

The STR05S2V5 is a high-performance DC-DC converter designed for use in a wide range of applications. It features synchronous rectification with a low quiescent current and is capable of providing a fully regulated low output voltage with high efficiency. This makes it an ideal choice for applications where power consumption and reliability are critical such as medical and military systems. The STR05S2V5 is also suitable for consumer electronics applications such as portable media players and power banks.
