(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.

As a member of the SWIFT™ 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 µA, 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.
