TI Korea (CEO Kent Chon, www.ti.com/ww/kr) June 27, 2014 – TI (CEO Kent Chon) announced the launch of two 18V, 20A and 30A synchronous DC/DC buck converters with PMBus interface. The SWIFT TPS544B20 and TPS544C20 converters are provided in a compact QFN package and feature integrated MOSFETs, enabling them to drive ASICs used in space-constrained, high power density applications across diverse markets including wired/wireless communications, enterprise and cloud computing, and data storage systems. When used with TI's award-winning WEBENCH® online design tool, this product simplifies power conversion and enables faster power supply design.

This highly integrated converter offers 0.5% reference voltage accuracy and fully implements differential remote voltage sensing to meet the voltage requirements of ultra-fine sub-micron processors. The selectable D-CAP™ or D-CAP2™ adaptive on-time control mode is easy to use, achieves very fast load transient response, and reduces the number of external components. Additionally, programmable functions, real-time monitoring of output voltage/current/external temperature, and fault reporting via PMBus simplify power supply design while simultaneously improving reliability and reducing component count and system cost.

For PMBus applications where output voltage, current, and board temperature telemetry are not required, TI provides the 12A SWIFT TPS53915 buck converter product.

The TPS544B20 and TPS544C20 feature integrated power MOSFETs supporting continuous output currents of 20A and 30A respectively, on-chip PMBus interface and non-volatile memory that simplify power supply design, provide voltage/current/temperature monitoring capability, and enable power supply customization.
Thanks to selectable D-CAP or D-CAP2 adaptive on-time control mode, output capacitors and external compensation networks are not required, minimizing the number of external components. Additional features include internal soft start, input under-voltage protection, and thermal shutdown.
