Working Principles

The LTC3412EUF is a step-down DC/DC converter that converts a higher input voltage to a lower output voltage. It utilizes a synchronous rectification architecture to achieve high efficiency. The internal control circuitry regulates the duty cycle of the switching transistor (SW pin) to maintain the desired output voltage. The feedback voltage (FB pin) is compared to an internal reference voltage to adjust the duty cycle accordingly. The soft-start function gradually ramps up the output voltage during startup to prevent excessive inrush current.
