TPS54372
SLVS430D – JUNE 2002 – REVISED FEBRUARY 2005
3-A OUTPUT TRACKING/TERMINATION SYNCHRONOUS PWM SWITCHER WITH
INTEGRATED FETs (SWIFT)
Tracks Externally Applied Reference Voltage
As a member of the SWIFT family of dc/dc regu-
lators, the TPS54372 low-input voltage, high-output
60-m
MOSFET Switches for High Efficiency
current, synchronous-buck PWM converter integrates
at 3-A Continuous Output Source or Sink
all required active components. Included on the
Current
substrate with the listed features are a true, high
6% to 90% VI Output Tracking Range
performance, voltage error amplifier that enables
Wide PWM Frequency: Fixed 350 kHz or
maximum performance under transient conditions
Adjustable 280 kHz to 700 kHz
and flexibility in choosing the output filter L and C
components; an undervoltage-lockout circuit to pre-
Load Protected by Peak Current Limit and
vent start-up until the input voltage reaches 3 V; an
Thermal Shutdown
internally and externally set slow-start circuit to limit
Integrated Solution Reduces Board Area and
in-rush currents; and a status output to indicate valid
Total Cost
operating conditions.
The TPS54372 is available in a thermally enhanced
20-pin TSSOP (PWP) PowerPAD package, which
DDR Memory Termination Voltage
eliminates bulky heatsinks. TI provides evaluation
Active Termination of GTL and SSTL
modules and the SWIFT designer software tool to
High-Speed Logic Families
aid in quickly achieving high-performance power
supply designs to meet aggressive equipment devel-
DAC Controlled, High-Current Output Stage
opment cycles.
