The device has a high efficiency up to 92% and also features a soft start function to minimize output voltage overshoot during turn-on.

The working principle of the QM48T50025-NCAP converter is based on the inductor-capacitor (LC) tank. It is a type of DC-DC converter in which a high-frequency oscillating circuit is used to convert a DC input into a high-frequency AC output. The transformer then steps up the oscillating voltage to the desired output voltage. The rectifier then converts the AC voltage into a DC voltage. The capacitor filter then smooths out the ripple from the DC output.

The output voltage of the QM48T50025-NCAP converter is regulated by the control circuit. The frequency of the oscillating circuit is controlled by varying the duty cycle of the switching transistors. The output voltage can also be adjusted through a voltage-setting circuit. All of these control circuits are integrated on the IC chip.

The QM48T50025-NCAP is a high efficiency, high power, variable frequency DC-DC converter that offers an interesting solution for applications requiring power and energy storing systems, distributed power systems, motor controls, and cost details. It has a wide input voltage range, high output power density and excellent energy efficiency. Thanks to its low profile design, it is also suitable for compact designs requiring maximum power density.
