High-current PMBus converters

6 August 2014 Power Electronics / Power Management

Texas Instruments introduced the industry’s first 18 V, 20 A and 30 A synchronous DC-DC buck converters with PMBus interface. The SWIFT TPS544B20 and TPS544C20 feature small QFN packages and integrated MOSFETs to drive ASICs in space-constrained and power-dense applications. They feature 0,5% reference voltage accuracy and fully differential remote voltage sensing to meet voltage requirements of deep sub-micron processors. Selectable D-CAP or D-CAP2 adaptive on-time control mode is easy to use and provides very fast load transient response, while programmability, real-time monitoring of the output voltage, current and external temperature, and fault reporting via PMBus simplify power supply design.
