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.
