 (TPS54xxx series) DC/DC Converter-based Power Management Solution 

Providing I

CCINT

=1.5A from V

IN

=5V 

 

SUPPORTS: 
 

Spartan™-3  

 
FEATURES: 
 

High efficiency minimizes heat 

Interchange SWIFT

T M

 device to support 1.5 A to 3 A load currents 

o

  1.5A (TPS54110) and 3A (TPS54310) synchronous SWIFT devices are 

pin-pin compatible 

Use of the TPS54x10 adjustable devices allow 

o

  use of smallest inductor and/or specific type of output capacitor 

o

  flexibility to re-compensate as needed, depending on the 

bypass/decoupling capacitors used with the FPGA  

In-rush current (for charging decoupling caps and FPGA start-up) that places a 
demand on the input power supply is minimized by the use of optional 

o

  Integrated soft-start configured with an capacitor to provide 10 ms rise 

time for V

CCINT

 and V

CCO

  

o

  Sequencing of V

CCINT

, V

CCAUX

, then V

CCO 

using

 

PWRGD and ENABLE 

High UVLO trip point and integrated soft-start of the SWIFT

T M

 devices 

eliminates the need for an external Supply Voltage Supervisor (SVS) to monitor 
the input rail. 

Additional V

CCO

 rails easily added and sequenced (if desired) using the TPS54xxx 

PWRGD and ENABLE. 

The design meets Xilinx’s V

CCINT

 and V

CCO

 start- up profile requirements, where 

applicable, including monotonic voltage ramp, in-rush current and power voltage 
ramp time requirements.
