Introduction
Speed and accuracy do not always go hand-in-hand in DC/DC converter systems—that is, until now. The LTC3811 is a dual output, fixed frequency current mode DC/DC switching regulator controller designed for one of today’s most demanding power supply applications: high current, low voltage processor core supplies.
With supply current requirements in excess of 100A and supply voltages as low as 1V, every milliohm of ...
