Texas Instruments Inc. (TI, Dallas, TX) announced its new TPS54910 SWIFT (switcher with integrated FET technology) high-performance, synchronous-buck, dc/dc converter that is suitable for powering point-of-load DSP, FPGA and micro-controller applications; networking and optical communications systems; and low-voltage, high-density, distributed power systems off a 3.3V bus.
The TPS54910 SWIFT converter with internal 12A peak MOSFETs is capable of supplying greater than 9A of continuous output current over the entire operating temperature range and functioning over a 3.0V to 3.6V input-voltage range. By integrating synchronous-buck power MOSFETs with control circuitry in a small 28-pin HTSSOP package, the device can provide more than 9A of continuous output current with less than 0.7in² of board space.
The TPS54910 offers a high output current while providing integrated protection features such as power-good, over-current protection, thermal shutdown and under-voltage lockout. An integrated synchronous rectifier and a low 15mW RDS(on) of the power MOSFETs enable the device to achieve efficiencies greater than 95 percent. In addition to the TPS54910, other fixed or adjustable output-voltage versions of the SWIFT family of dc/dc converters are available with 2.0 percent total accuracy.
