DESCRIPTION
As a member of the SWIFT™ family of dc/dc regulators, the TPS54010 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 under
transient conditions and flexibility in choosing the output filter L and C components; an undervoltage-lockout
circuit to prevent start-up until the VIN input voltage reaches 3 V; an internally and externally set slowstart circuit
to limit in-rush currents; and a power-good output useful for processor/logic reset, fault signaling, and supply
sequencing.
The TPS54010 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which
eliminates bulky heatsinks.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
