This slide shows a comparison of the LTC3877 to the LTC3875, and LTC3774. All these parts are dual output synchronous step-down current mode controllers that operate over a 4.5V to 38V input voltage range. The LTC3877 has benefits that include VID control, tighter output voltage accuracy, and a lower minimum on time that allows for a higher step-down ratio power supply at a given operating frequency.
