Working Principles

The LTC3204EDC-5#TRMPBF is a step-up DC/DC converter that converts a low input voltage to a higher output voltage. It utilizes a switching regulator topology to efficiently boost the input voltage. The feedback pin (FB) allows the user to set the desired output voltage by adjusting the resistive divider connected to it.

When enabled, the internal control circuitry generates a high-frequency signal that drives the switching transistor. This causes energy to be transferred from the input to the output through an inductor and capacitor network. The output voltage is regulated by comparing it to a reference voltage at the feedback pin, ensuring stability and accuracy.
