DC DC Converters

DC DC converters are devices that convert a direct current (DC) voltage at one level to a voltage at another level. They are also used as switches to regulate the intensity of a light-emitting diode (LED) or other semi-conductor devices. There are many different types of DC DC converters available, depending on the application. Some of the most common are step-up converters, step-down converters, forward converters, and flyback converters.

RP40-4815SFR/P-HC Application Field

RP40-4815SFR/P-HC is a non-isolated step-down DC DC converter. It is suitable for low-power consumer and portable electronics applications, such as digital cameras, handheld game consoles, media players, portable power sources, and portable LED lighting devices. This converter is capable of a wide input voltage range of 6-36V and is able to control current up to 1.5A at a fixed output voltage of 5V.

Working Principle

The working principle of RP40-4815SFR/P-HC can be divided into three parts: rectifying, filtering, and buck switching. In the rectifying stage, an AC voltage is first rectified and then filtered, before it is sent to the buck switching stage. The buck switching stage converts the rectified voltage into a lower, fixed-voltage DC output. The output voltage is controlled by a loop containing an oscillator and a pulse-width modulated circuit.

Features and Benefits

The RP40-4815SFR/P-HC is capable of up to 95% efficiency, which makes it very efficient when dealing with power distribution. It also has low ripple and noise, and low quiescent current. The overcurrent and overvoltage protection features provide overcurrent and overvoltage protection in real time. Additionally, this converter is packaged in an industry-standard SIP7 form factor, making it easier to mount on a PCB board.

Conclusion

The RP40-4815SFR/P-HC is a high performance non-isolated step-down DC DC converter which is suitable for a wide range of low power applications. It has excellent efficiency, low ripple and noise, low quiescent current, and offers overcurrent and overvoltage protection. Its industry-standard form factor makes it easy to mount on a PCB board, making it an ideal choice for portable electronics and consumer applications.
