TPS54618 Down SWIFT™ DC/DC Converter



Texas Instruments' 2.95V~6V input, 6A, 2MHz synchronous step down converter

Texas Instruments TPS54618 Down SWIFT™ DCDC Converter Texas Instruments' TPS54618 device is a full featured 6V, 6A, synchronous step down current mode converter with two integrated MOSFETs. The TPS54618 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external component count, reducing inductor size by enabling up to 2MHz switching frequency, and minimizing the IC footprint with a small 3mm × 3mm thermally enhanced QFN package. The TPS54618 provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over temperature. Efficiency is maximized through the integrated 12µΩ MOSFETs and 515µA typical supply current. Using the enable pin, shutdown supply current is reduced to 5.5µA by entering shutdown mode.

  Features   Applications
