DESCRIPTION
The SWIFT family of dc/dc regulators, the TPS54611,
TPS54612, TPS54613, TPS54614, TPS54615, and
TPS54616 low-input voltage high-output current
synchronous-buck PWM converters integrate all required
active components. Included on the substrate are true,
high-performance, voltage error amplifiers that provide
high performance under transient conditions; an
under-voltage-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.
The TPS54611−6 devices are available in a thermally
enhanced 28-pin TSSOP (PWP) PowerPAD package,
which eliminates bulky heatsinks. Texas Instruments
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.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
