SLUSBV0A – MAY 2014 – REVISED JULY 2014 TPS40428 Dual Output, 2-Phase, Stackable PMBus™ Synchronous Buck Driverless
Controller with Adaptive Voltage Scaling (AVS) Bus
1 Features 3 Description The TPS40428 device is a PMBus, synchronous
buck, driverless controller. It operates in smart power
mode with factory default settings, and it can operate
in non-smart power mode after PMBus programing
and power reboot. It can be configured for dualoutput or 2-phase operation. 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 Smart Power Mode in Factory Default (Compatible
with TI Smart Power Stage CSD95378B and Pinfor-Pin Equivalent to TPS40425 – Non-Smart
Power Mode in Factory Default)
Single Supply Operation: 4.5 V to 20 V
