TPS54618 Down SWIFT™ DC-DC Converter

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

TPS54618 Down SWIFT™ DC/DC ConverterTexas Instruments' TPS54618 device is a full featured 6 V, 6 A, 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 2 MHz switching frequency, and minimizing the IC footprint with a small 3 mm × 3 mm 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 12 µΩ MOSFETs and 515 µA typical supply current. Using the enable pin, shutdown supply current is reduced to 5.5 µA by entering shutdown mode.

Features Applications
  • Two 12 mΩ (typical) MOSFETs for high efficiency at 6 A loads
  • 0.8 V ±1% voltage reference over temperature (-40°C to 150°C)
  • Synchronizes to external clock
  • Adjustable slow start/sequencing
  • UV and OV power good output
  • –40°C to 150°C operating junction temperature range
  • Thermally enhanced 3 mm × 3 mm 16-pin QFN
  • Pin compatible to TPS54418
  • Low-voltage, high-density power systems
  • Point of load regulation for high performance DSPs, FPGAs, ASICs, and microprocessors
  • Broadband, networking, and optical communications infrastructure
