Working Principles

LTC3604IUD operates as a synchronous buck regulator, converting the input voltage to a lower, regulated output voltage. It utilizes a high-frequency switching technique to efficiently step down the voltage. The feedback voltage (FB) pin is used to set the desired output voltage, while the enable (EN) pin controls the device's on/off state. The power good indicator (PG) pin provides a signal indicating when the output voltage is within the specified range.
