LTC3882-Slide7

This slide shows a comparison of the LTC3882 to the LTC3880/-1, both parts are a digital power system management dual output synchronous step-down controllers. The LTC3882 has a voltage mode control architecture, whereas the LTC3880 uses current mode control. Voltage mode control allows the use of a lower DCR inductor resulting is higher output current capability and higher efficiency. The LTC3882 operates over a 3V to 38V input voltage range, whereas the LTC3880 operates over a lower 4.5V to 24V input voltage range. The LTC3882 can produce an output voltage ranging from 0.5V to 5.25V for both outputs. The LTC3880 has onboard N-channel MOSFET gate drivers, whereas the LTC3882 does not have gate drivers. The LTC3882 has a tri state output used for driving external gate drivers and MOSFET or can be used with DrMOS and Power Blocks.
