DESCRIPTION/ORDERING INFORMATION
As a member of the SWIFT™ family of dc/dc
regulators, the TPS54610 low-input voltage
high-output current synchronous buck PWM
converter integrates all required active components.
Included on the substrate with the listed features are
a true, high-performance, voltage error amplifier that
enables maximum performance and flexibility in
choosing the output filter L and C components, an
under-voltage-lockout circuit to prevent start-up until
the input voltage reaches 3 V, an internally or
externally set slow-start circuit to limit inrush currents, and a power good output useful for processor/logic
reset, fault signaling, and supply sequencing.
The TPS54610 is 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.
