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 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.

The wide input voltage range can support 5-V and 12-V intermediate supply buses. The 0.5% reference voltage satisfies the need of precision voltage to the modern ASICs.

Using the PMBus standard, the TPS40428 device can program reference voltage, fault limit, UVLO threshold, soft-start time and turn-on and turn-off delay.

In addition, the device implements an accurate measurement system to monitor the output voltages, currents and temperatures for individual channels.

For all available packages, see the orderable addendum at the end of the data sheet.
