Speed and accuracy don’t 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. Multiphase DC/DC Controller Pushes Accuracy and Bandwidth Limits Design Note 434 Tick Houk Introduction In addition to high accuracy, the LTC3811’s low mini- Speed and accuracy don’t always go hand-in-hand mum on-time (typically 65ns) allows users to convert a in DC/DC converter systems―that is, until now. The 12V input to a 1V output at switching frequencies up to LTC3811 is a dual output, xed frequency current mode 750kHz, optimizing load transient response and reducing DC/DC switching regulator controller designed for one of the soluti……
