4.5-V TO 20-V INPUT, 6-A OUTPUT SYNCHRONOUS PWM  
SWITCHER WITH INTEGRATED FET (SWIFT)  
FEATURES  
DESCRIPTION  
40 mMOSFET Switch for High Efficiency at  
6-A (7.5 Peak) Output Current  
The TPS54550 is  
synchronous buck PWM converter with an integrated  
high side MOSFET and a gate driver for an low side  
a
medium output current  
Uses External Lowside MOSFET  
external MOSFET. Features include  
a
high  
Output Voltage Adjustable Down to 0.891 V  
With 1% Accuracy  
performance voltage error amplifier that enables  
maximum performance under transient conditions  
and flexibility in choosing the output filter inductors  
Synchronizes to External Clock  
and  
capacitors.  
The  
TPS54550  
has  
an  
180° Out of Phase Synchronization  
under-voltage-lockout circuit to prevent start-up until  
the input voltage reaches 4.5 V; a 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.  
Wide PWM Frequency– Fixed 250 kHz,  
500 kHz or Adjustable 250 kHz to 700 kHz  
Adjustable Slow Start  
Adjustable Undervoltage Lockout  
Load Protected by Peak Current Limit and  
Thermal Shutdown  
The TPS54550 device is available in a thermally  
enhanced 16-pin TSSOP (PWP) PowerPAD™  
package. TI provides evaluation modules and the  
SWIFT™ Designer software tool to aid in quickly  
achieving high-performance power supply designs to  
meet aggressive equipment development cycles.
