(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
APPLICATIONS
• Low-Voltage, High-Density Distributed Power
Systems
• Point-of-Load Regulation for High-
Performance DSPs, FPGAs, ASICs, and
Microprocessors
• Broadband, Networking, and Optical
Communications Infrastructure
• Portable Computing/Notebook PCs
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.
