DC-DC converters are electronic components that convert one DC voltage level to another. They are typically used to increase or decrease the power from a power supply or battery, and may also provide protection or regulation for the power or voltage being supplied. The SSQE48T25015-NAB0G DC-DC converter is designed to convert a wide range of DC input voltages, from 12V to 48V, and is suitable for applications requiring a variable DC output voltage in the range of 4.5V to 15V.

Applications

The SSQE48T25015-NAB0G is designed to provide high efficiency, high output power, and cost-effectiveness in a wide range of applications. These include general purpose electronic applications, battery-powered systems, communications systems, RF & microwave systems, automotive systems, and power management systems. The high efficiency of the converter allows it to operate with up to 93% efficiency in wide input/output power level combinations, thereby reducing power consumption and improving battery life.

Working Principle

The SSQE48T25015-NAB0G works by first converting the DC input voltage to an AC signal using one or more integrated, full-bridge switching circuits. This signal is then applied to a transformer to isolate the input and output, and reduce the voltage to the desired level. The output of the transformer is then rectified to produce an isolated, regulated DC output voltage.

The full bridge switching circuit is controlled by a Pulse Width Modulation (PWM) circuit which can vary the output voltage by changing the pulse width of the signal. The PWM circuit is typically an integrated loop regulated circuit that regulates the output voltage according to a reference voltage. This reference voltage can be adjusted and fine-tuned in order to achieve the desired output voltage. The switch-over frequency is typically set to a frequency that is above the audible range to reduce audible noise.

The SSQE48T25015-NAB0G features an over-voltage protection circuit which monitors the output voltage and switches the converter off if it exceeds a set limit. It also features short-circuit protection, current limiting, and thermal protection. The thermal protection circuit monitors the temperature of the integrated switching circuit, and will shut off the converter if the temperature exceeds a set limit. These features ensure a long and reliable operation of the converter even in adverse conditions.

Conclusion

The SSQE48T25015-NAB0G is a high efficiency DC-DC converter designed to provide a wide range of output voltages from a wide range of input voltages. It’s suitable for a variety of applications and provides many features to ensure reliable operation. If you need to power a device with a wide range of input voltages, the SSQE48T25015-NAB0G is a great choice.
