Texas Instruments Incorporated (Dallas, TX) (TI) (NASDAQ: TXN) has introduced two 3.5-A step-down DC/DC converters with an integrated MOSFET and industry-leading reference accuracy of one percent. The TPS54360 and TPS54340 join TI’s family of Eco-Mode SWIFT DC/DC converters that operate over a wide input range with low operating and shutdown quiescent current. Features include:

  • An input range from 4.5 to 60 V (TPS54360) or 42 V (TPS54340).
  • Robust input voltage protection.
  • Current mode control that allows simple external compensation and flexible component selection.
  • An integrated 92-mOhm high-side MOSFET.
  • A low dropout operating mode, approaching 100 percent duty cycle.
