Working Principle

The principle of operation for the LTC3630AHDHC#TRPBF is based upon a circuit which integrates both a Switching Regulator and a Linear Regulator. The switching regulator acts as a power supply for the linear regulator, which supplies current to the output load. The linear regulator is powered via the switching regulator, and the switching regulator is powered by the input voltage. This allows for a wide input voltage range being supported, as well as reducing overall noise.

The switching regulator operates in a pulse width modulation (PWM) mode, whereby it switches on and off at regular intervals based on a given frequency. By varying the duty cycle of the switching regulator during this cycle, the output voltage and current can be adjusted. This occurs while the linear regulator maintains a constant current output, resulting in an overall reduction in power consumption.

The linear regulator is used to provide a stable voltage reference, and is not simply used to regulate the output of the switching regulator. This provides an additional advantage as the linear regulator can be adjusted more finely, allowing for more precise power delivery for sensitive applications.

The LTC3630AHDHC#TRPBF is a versatile switching regulator and linear regulator combination, offering both a high power delivery range and a low output voltage and current, making it ideal for a range of applications.
