The SQM48T20010-NBBP utilizes a PWM (pulse width modulation) technique to regulate the output voltage. The PWM technique works by controlling the on/off time of the switching MOSFETs. This allows for a low ripple output voltage, as only the MOSFETs will turn on and off periodically. The PWM technique also provides a high efficiency, as it allows the converter to regulate the output voltage with minimal losses.

The primary components of the SQM48T20010-NBBP are the switching MOSFETs, power transformer, control IC, and EMI filter. The switching MOSFETs are used to control the input switching power supply to the transformer. The power transformer is responsible for converting the input power to the desired output voltage. The control IC is used to regulate the input power and generate the necessary signals for controlling the switching MOSFETs. Finally, the EMI filter is used to filter out any interference signals created by the switching MOSFETs, ensuring a clean and noise-free output power.

Overall, the SQM48T20010-NBBP is an ideal choice for applications requiring an isolated and regulated DC output. It is highly reliable, offers a wide range of features, and can be used in a variety of applications. Additionally, its compact size and high power density make it suitable for space constrained applications.
