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.
