DC-DC converters are electrical devices that are used in a wide range of applications, from industrial processes to everyday consumer electronics. The SPM25-033-D48P-C is one such converter from RECOM Power. In this article, we will outline the main application field and working principle of the SPM25-033-D48P-C converter.

The SPM25-033-D48P-C is a DC-DC converter designed for high efficiency applications. It has a rated input voltage of 8V - 30V and an input current up to 5A. It also features two isolated, 0 - 5V regulated output channels, offering currents of up to 3A each. The whole unit is just 40.3 x 25.6 x 10.7mm and comes with protection features, such as short-circuit, over-temperature, and input surge protection.

The SPM25-033-D48P-C is ideally suited to applications that require efficient, reliable power, such as industrial automation, automotive, metering, and HVAC systems. It is also suitable for powering device peripherals, such as rugged displays, modems, sensors and storage drives. The unit can also be used in negative voltage applications, using the “inverted” pinout option.

The SPM25-033-D48P-C uses a buck switching topology to convert input voltage into a lower output voltage. This is a PWM (pulse-width modulation) controller that switches a MOSFET (metal-oxide-semiconductor field-effect transistor) at a high frequency. This allows the converter to produce a continuous output voltage with very little loss. For added protection, the unit also includes an over-voltage and under-voltage lockout circuit, as well as an over-current protection circuit.

The SPM25-033-D48P-C has an adjustable switching frequency up to 2MHz and it can operate in constant current, constant voltage, and constant power modes. It also features a 6-bit digital control interface, which allows for automated system control. The unit can be controlled remotely using its built-in digital logic and communication interfaces, such as the I2C bus.

The efficiency of the SPM25-033-D48P-C converter is typically up to 95%, and it has a nominal operating temperature range of -40° to +85°C and a storage temperature range of -55° to +125°C. The unit is also RoHS compliant.

In conclusion, the SPM25-033-D48P-C is a DC-DC converter from RECOM Power designed for efficient, reliable power. It has a rated input voltage of 8V - 30V, two 0 - 5V regulated output channels offering currents of up to 3A each, and protection features such as over-voltage and under-voltage lockout, over-current protection, and temperature protection. It has an adjustable switching frequency, automated control via a digital logic interface, and is typically 95% efficient at full load. These features make it ideal for applications such as industrial automation, automotive, metering, and HVAC systems. It is also suitable for negative voltage applications using the “inverted” pinout option.
