Working Principle:

The LT3472EDD#TRPBF uses a fixed frequency voltage mode control topology. This is a common way to regulate voltage output because it reduces design time and eliminates the need for external compensation components. The device has four internal switches that can be used to construct either a synchronous buck, non-synchronous buck, boost or inverting topology.

The device features a user selectable output voltage range that can be set to between 2.5 V and 75 V without the need for external components. To control the output voltage, an error amplifier compares the feedback voltage to a reference voltage and adjusts the switches accordingly. The output voltage is regulated to achieve the desired voltage as set by the external feedback resistors.

This fixed frequency voltage mode control allows for easier implementation and also has inherent protections, such as over-current protection and over-temperature protection, which is provided by the onboard temperature monitor.
