QPDS15-48S3.3

DC-DC converters are used to transfer electrical energy from one voltage level to another in order to provide regulated current or voltage output. The QPDS15-48S3.3 DC-DC converter is an adjustable single-channel isolated DC-DC converter module that is designed for applications where a wide input voltage range is required.The QPDS15-48S3.3 DC-DC converter has a wide input voltage range of 18-36 volts DC with an adjustable output voltage range of 3.3-14 volts DC. It also features a maximum continuous output current of 25A with peak output currents of up to 48A. The module is also equipped with active current limiting, short-circuit and over-temperature protection as well as over-voltage protection.The QPDS15-48S3.3 DC-DC converter can be used in many different applications. It is commonly used in industrial control systems, battery charging systems, power backup systems, and other power supply applications. It is also used for powering on-board electronic devices in automotive applications.The module works by converting the DC input voltage to a higher voltage, or a lower voltage depending on the application needs. It uses a switching regulator integrated circuit (IC) to control the current, voltage, or power output.The switching regulator IC is responsible for controlling the current and voltage output of the module. It works by turning on and off transistors that are connected to the input and output of the module. When the transistor is on, the input voltage is connected directly to the output and when it is off, the output is disconnected from the input voltage. This creates a pulse-width modulation of the input voltage, which is then converted to an adjustable output voltage to provide regulated current or voltage output.The switch regulator IC is powered by a voltage reference, which is usually a precision voltage divider. This reference voltage is then divided by a feedback loop to set the desired output voltage. When the output voltage deviates from the reference voltage, the switching IC turns on or off the transistors, which in turn adjusts the pulse-width modulation to close the voltage difference.The QPDS15-48S3.3 DC-DC converter is a powerful, reliable, and efficient power conversion solution. It is a cost-effective solution for low-power applications that require flexibility and stability. It is also a popular choice for automotive applications due to its wide operating range and its ability to handle high peak currents.
