Texas Instruments TPS40422 Dual Output Synchronous Buck Controller

Texas Instruments TPS40422 is a dual-output PMBus synchronous buck controller that can also be configured for a single, two-phase output. The wide input range of the TI TPS40422 can support 5V and 12V intermediate buses. The accurate reference voltage satisfies the need of precision voltage to modern ASICs and potentially reduces the output capacitance. Voltage mode control is implemented to reduce noise sensitivity and also ensures low duty ratio conversion. The TPS40422 margining function, reference voltage, fault limit, UVLO threshold, soft start time and turn on/off delay can be programmed using the PMBus protocol. This TI synchronous buck controller also features an accurate measurement system to monitor the output voltages, currents and temperatures for each channel. TPS40422 is ideal for use in a variety of applications, including multiple rail systems and telecom base stations.
