FEATURES
DESCRIPTION
The TPS54519 device is a full featured 6 V, 5 A,
Two 30 m
(typical) MOSFETs for high
synchronous step down current mode converter with
efficiency at 5-A loads
two integrated MOSFETs.
200kHz to 2MHz Switching Frequency
The TPS54519 enables small designs by integrating

3mm thermally enhanced QFN package.
Low Operating and Shutdown Quiescent
Current
The TPS54519 provides accurate regulation for a
variety of loads with an accurate
