**Description:** TheTPS54318 device is a full featured 6-V, 3-A, synchronous, step-down, current mode converter with two integrated MOSFETs. The TPS54318 device 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 device footprint with a small, 3 mm x 3 mm, thermally enhanced, QFN package. **Feature:** Features Two, 30-mΩ (typical) MOSFETs for High-Efficiency at 3-A loads Switching Frequency: 200 kHz to 2 MHz Voltage Reference Over Temperature: 0.8 V ± 1% Synchronizes to External Clock Adjustable Soft-start/Sequencing UV and OV Power Good Output Low Operating and Shutdown Quiescent Current Safe Start-up into Pre-Biased Output Cycle-by-Cycle Current Limit, Thermal and Frequency Fold Back Protection Operating Junction Temperature Range: –40°C to 150°C Thermally Enhanced 3 mm × 3 mm 16-pin WQFN Package
