The high efficiency, wide input voltage range, and compact size make it ideal for applications that require high power in a small package.

Working Principle

The RPA30-2405SAW-HC DC-DC converter converts a single DC input source into multiple outputs. The transformer is used to step down the voltage from the input to the desired output. The output is regulated using a circuit composed of an integrated current and time (COT) controller that drives a transistor switch. The transistor switch is connected to the input. When the transistor switch is open, current cannot flow, and the output voltage is stabilized. The circuit also uses feedback, which is used to compare the output voltage with the desired setpoint. When the output signal varies from its setpoint, the circuit adjusts the output voltage.

The RPA30-2405SAW-HC DC-DC converter has a built-in power protection circuit. This circuit monitors the input voltage and shuts down the converter if an overvoltage or undervoltage is detected. This ensures that components connected to the output remain protected from any voltage spikes or drops. The converter also comes equipped with ESD protection, short-circuit protection, and over-current protection, which protects all components from any external disturbances.

Conclusion

The RPA30-2405SAW-HC is an efficient, cost-effective DC-DC converter from XP Power that is suitable for use in a variety of applications, such as networking, telecom/server/industrial applications, as well as in embedded devices and automotive equipment. It features a wide input voltage range with adjustable output voltage, low-profile design, reduced acoustic noise, high peak efficiency, and built-in power protection and ESD protection circuits.
