DC DC Converters

DC-DC converters are electrical devices that are used to convert the voltage of a direct current (DC) to a different output voltage. The DC-DC converter types generally used are non-isolated point of load (POL) converters, DC to single-phase AC inverters, and high-voltage modules. This article focuses on the RPM60-2412SG/N, one of the more popular DC-DC converter types.

RPM60-2412SG/N Application Field

The RPM60-2412SG/N is typically used in industrial automation, communications, data storage, instrumentation, military, and medical applications. It is suitable for high-reliability critical applications and point-of-load designs where high efficiency and long life is required. The device offers:

• Constant-current and constant-voltage specifications
• Input voltage range from 18V to 36V
• Output voltage range from 12V to 24V
• High efficiency and long life

RPM60-2412SG/N Working Principle

The RPM60-2412SG/N utilizes a non-isolated buck-boost topology. It converts an input voltage to a constant output voltage, regardless of changes in the input voltage. The device works on two distinct modes, providing either constant current or constant voltage as per the load requirements. The constant current mode limits the output current to the set value, whereas the constant voltage mode limits the output voltage to the set value.

The device also features a differential amplifier which provides control current to the pulse-width modulation (PWM) control IC. This control IC generates a PWM signal with a fixed frequency, usually 500kHz to 2Mhz. The PWM signal is then fed to the power transistor switching circuit, which switches the circuit on and off at the specific duty cycle determined by the PWM signal. As a result, the input voltage is regulated to the desired voltage level as per the set value.

The RPM60-2412SG/N adopts a special circuit to realize reverse current protection when the input exceeds the output voltage. This reverse current protection prevents the device from being damaged when it is subjected to an abnormal input voltage. The device also features over-temperature protection which shuts off the output current in case of over-temperature.

Conclusion

The RPM60-2412SG/N is a popular DC-DC converter type that is designed for industrial automation, communications, data storage, instrumentation, military, and medical applications. The device offers an input voltage range of 18-36V and an output voltage range of 12-24V, with high efficiency and long life. The non-isolated buck-boost topology it utilizes provides constant current and constant voltage operation based on the load requirements. Furthermore, the device uses several functionalities to guarantee its safety and reliability, such as reverse current protection and over-temperature protection.
