www.ti.com SLVSAT3A – SEPTEMBER 2011 – REVISED DECEMBER 2013 2.95 V to 6 V Input, 5-A Synchronous Step Down SWIFT™ Converter
FEATURES DESCRIPTION The TPS54519 device is a full featured 6 V, 5 A,
synchronous step down current mode converter with
two integrated MOSFETs. 1 2 Two 30 mΩ (typical) MOSFETs for high
efficiency at 5-A loads
200kHz to 2MHz Switching Frequency
0.6 V Voltage Reference With В± 1% Initial
Accuracy
Adjustable Slow 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
–40°C to 140°C Operating Junction
Temperature Range
Thermally Enhanced 3mm Г— 3mm 16-pin QFN The TPS54519 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 3mm x …
