SLUSBO6B – JANUARY 2014 – REVISED DECEMBER 2016 TPS40425 Dual Output, 2-Phase, Stackable PMBus™ Synchronous Buck Driverless
Controller with Adaptive Voltage Scaling (AVS) Bus
1 Features 3 Description The TPS40425 is a PMBus, synchronous buck,
driverless controller. It operates in non-smart power
mode in factory default setting, and it can operate in
smart power mode after PMBus programming and
power reboot. It can be configured as dual-output or
2-phase. It is also stackable up to 4 phases to
support load current as high as 120 A. Interleaved
phase shift for 2-, 3-, or 4-phases reduce the input
and output ripples therefore reducing input and output
capacitance. 1 Non-Smart Power Mode in Factory Default
