Two 30 m
(typical) MOSFETs for high
efficiency at 4 A loads
The TPS54418 device is a full featured 6 V, 4 A,
synchronous step down current mode converter with
200kHz to 2MHz Switching Frequency
two integrated MOSFETs.
0.8 V ± 1% Voltage Reference Over
Temperature
The TPS54418 enables small designs by integrating
the MOSFETs, implementing current mode control to

size by enabling up to 2 MHz switching frequency,
UV and OV Power Good Output
and minimizing the IC footprint with a small 3mm x
3mm thermally enhanced QFN package.
Low Operating and Shutdown Quiescent
Current
The TPS54418 provides accurate regulation for a
variety of loads with an accurate ±1% Voltage
Safe Start-up into Pre-Biased Output
Reference (VREF) over temperature.
Cycle by Cycle Current Limit, Thermal and
Frequency Fold Back Protection
Efficiency is maximized through the integrated 30m
MOSFETs and 350mA typical supply current. Using
–40°C to 150°C Operating Junction
the enable pin, shutdown supply current is reduced to
