FEATURES  
DESCRIPTION  
D
100 m, 4.5-A Peak MOSFET Switch for High  
Efficiency at 3-A Continuous Output Current  
The TPS54350 is a medium output current synchronous  
buck PWM converter with an integrated high side  
MOSFET and a gate driver for an optional low side  
external MOSFET. Features include a high performance  
voltage error amplifier that enables maximum  
performance under transient conditions and flexibility in  
choosing the output filter inductors and capacitors. The  
TPS54350 has an under-voltage-lockout circuit to prevent  
start-up until the input voltage reaches 4.5 V; an internal  
slow-start circuit to limit in-rush currents; and a power good  
output to indicate valid output conditions. The  
synchronization feature is configurable as either an input  
or an output for easy 180° out of phase synchronization.

16-Pin TSSOP PowerPADE Package  
The TPS54350 device is available in a thermally  
enhanced 16-pin TSSOP (PWP) PowerPADpackage.  
TI provides evaluation modules and the SWIFTDesigner  
software tool to aid in quickly achieving high-performance  
power supply designs to meet aggressive equipment  
development cycles.
