Texas Instruments (TI) has 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 converters feature small QFN packages and integrated MOSFETs to drive ASICs in space-constrained and power-dense applications in various markets, including wired and wireless communications, enterprise and cloud computing, and data storage systems. Used in conjunction with TI's WEBENCH online design tools, the converters simplify power conversion and speed the power supply design process.
The highly integrated converters 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, provides very fast load transient response and reduces external component count. Programmability, real-time monitoring of the output voltage, current and external temperature, and fault reporting via PMBus simplifies power supply design, increases reliability and reduces component count and system cost.
