Working Principle

LTC3882EUJ-1#PBF contains a high-side gate driver, an error amplifier and a control logic circuit to provide accurate regulation of the output voltage. The output voltage regulation of this device is based on a voltage divider whose output is compared to an internal reference of 1.21 V. If the divided voltage is greater than the internal reference voltage, the error amplifier output will swing to a logic low level, and the control logic will switch the MOSFET on for a certain period of time. The duration of the MOSFET switching on can be adjusted via the on-time voltage, which is adjustable from 0.6 V to the input voltage in 50 mV increments.When the MOSFET is off, the inductor current decreases, and the output voltage adjusts itself to the desired value. By controlling the on-time voltage, the output voltage can be adjusted to an optimal value. The output ripple voltage, output noise and stability issues can also be minimized.
