G5193 Datasheet Synchronous Step Down

Manufacturer: Global Mixed-mode Technology

Overview: Global Mixed-mode Technology G5193 High Efficiency, 3A Output, Synchronous Step.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The G5193 device is a full featured 5.5V, 3A synchronous step down current mode converter with two integrated MOSFETs.

The G5193 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external ponent count, reducing inductor size by enabling up to 2MHz switching frequency, and minimizing the IC footprint with a small 3mm x 3mm thermally enhanced QFN package.

The G5193 provides accurate regulation for a variety of loads with an accurate ±1% Voltage Reference (VREF) over temperature.

Key Features

  • Two 45mΩ (typical) MOSFETs for high efficiency at 3A loads.
  • 300kHz to 2MHz Switching Frequency.
  • 0.827V±1% Voltage Reference Over Tempera- ture.
  • Synchronizes to External Clock.
  • Adjustable Soft Start.
  • UV and OV Power Good Output.
  • Low Operating and Shutdown Quiescent Cur- rent.
  • Safe Start-up into Pre-Biased Output.
  • Cycle by Cycle Current Limit, Thermal and Frequency Fold Back Protection.
  • Thermally Enhanced 3m.
