3 Description
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 HTSSOP (PWP) PowerPAD™ package, which
eliminates bulky heatsinks. TI 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.
