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.

DESCRIPTION/ORDERING INFORMATION
As a member of the SWIFT鈩?family of dc/dc regulators, the TPS5420 is a high-output-current PWM converter
that integrates a low-resistance high-side N-channel MOSFET. Included on the substrate with the listed features
is a high-performance voltage error amplifier that provides tight voltage regulation accuracy under transient
conditions, an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 5.5 V, an internally
set slow-start circuit to limit inrush currents, and a voltage feed-forward circuit to improve the transient response.
Using the ENA pin, shutdown supply current is reduced to 18
碌A(chǔ),
typically. Other features include an active high
enable, overcurrent protection, and thermal shutdown. To reduce design complexity and external component
count, the TPS5420 feedback loop is internally compensated.
The TPS5420 device is available in an easy to use 8-pin SOIC package. 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.
