The TPS40422 is a dual-output PMBus protocol, synchronous buck controller. It can be configured also for a single, two-phase output.
The wide input range supports 5-V and 12-V intermediate buses. The accurate reference voltage satisfies the need of precision voltage to the modern ASICs and potentially reduces the output capacitance. Voltage mode control reduces noise sensitivity and also ensures low duty ratio conversion.
