Working Principle

The QBW018A0B7-P is a step-down power converter that takes an input voltage from 48VDC or lower and steps down the voltage to an output voltage of 12VDC. This is achieved through a process of buck conversion. In buck conversion, voltage from the input source is converted to an intermediate DC voltage, which is then used to drive a sub-circuit switch to regulate the desired output voltage.

To achieve efficient voltage conversion, the switch connects the input and output capacitors using a synchronous rectifier bridge. This bridge is synchronized with the output voltage to regulate the output voltage. The output voltage is further regulated by an integrated control circuit, which also controls the number of pulses per second and duty cycle for efficient switching.

In addition, this converter also has a wide input voltage range, allowing it to be used in applications that require variable input voltages. It also has protection features such as over-current, over-voltage, and over-temperature protection. It is also short-circuit protected, ensuring safe operation.
