FEATURES  
DESCRIPTION  
D
100 m, 4.5-A Peak MOSFET Switch for High  
Efficiency at 3-A Continuous Output Current  
Uses External Lowside MOSFET or Diode  
Fixed Output Versions −  
1.2V/1.5V/1.8V/2.5V/3.3V/5.0V  
Internally Compensated for Low Parts Count  
Synchronizes to External Clock  
1805 Out of Phase Synchronization  
Wide PWM Frequency − Fixed 250 kHz,  
500 kHz or Adjustable 250 kHz to 700 kHz  
Internal Slow Start  
Load Protected by Peak Current Limit and  
Thermal Shutdown  
Adjustable Undervoltage Lockout  
The TPS5435x 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. The TPS5435x  
has an under-voltage-lockout circuit to prevent start-up  
until the input voltage reaches a preset value; 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.

The TPS5435x devices are 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.
