TPS40428RHAR Integrated Circuit Chip 2 Phase Synchronous Buck Driverless Controller

TPS40428RHAR Integrated Circuit Chip 2 Phase Synchronous Buck Driverless Controller​

Product Description Of TPS40428RHAR

TPS40428RHAR 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.
TPS40428RHAR can be configured for dual-output 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.
