The SWIFT TPS544B20 and TPS544C20 converters feature small QFN packages and integrated MOSFETs to drive ASICs in space-constrained and power-dense applications. 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 today's 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.
In a 40-pin, 5 x 7 x 1 mm QFN package, the 20-A TPS544B20 is priced at $3.70 and the 30-A TPS544C20 is priced at $3.90 (1000).
