FEATURES  
DESCRIPTION  
23  
•
30-mΩ MOSFET Switches for High Efficiency  
at 6-A Continuous Output  
As a member of the SWIFT™ family of dc/dc  
regulators, the TPS54617 low-input voltage  
high-output current synchronous buck PWM  
converter offers the same features as the TPS54610  
in a small package and higher switching frequency.  
Included on the substrate with the listed features are  
a true, high performance, voltage error amplifier that  
enables maximum performance under transient  
conditions and flexibility in choosing the output filter L  
and C components; an undervoltage-lockout circuit to  
prevent start-up until the input voltage reaches 3 V;  
an internally and externally set slow-start circuit to  
limit in-rush currents; and a power good output useful  
for processor/logic reset, fault signaling, and supply  
sequencing.  
•
Adjustable Output Voltage Down to 0.9 V With  
1% Accuracy  
•
•
Externally Compensated for Design Flexibility  
Wide PWM Frequency: Fixed 350 kHz, 550 kHz,  
or Adjustable 280 kHz to 1.6 MHz  
•
•
Synchronizable to 1.6MHz  
Load Protected by Peak Current Limit and  
Thermal Shutdown  
•
•
Small 3.5mm x 7mm Package and Similar  
Layout to TPS54610 Reduces Board Area and  
Total Cost  
SWIFT Documentation Application Notes, and  
SwitcherPro™ Software: www.ti.com/swift  
The TPS54617 is available in a thermally enhanced  
34 pin QFN (RUV) PowerPAD™ package, which  
eliminates bulky heatsinks. TI provides evaluation  
modules and the SwitcherPro™ design software tool  
to aid in achieving high-performance power supply  
designs to meet aggressive equipment development  
cycles.
