Overview
As a member of the SWIFT™ family of DC/DC regulators, the TPS5430 is a high-output-current PWM converter that integrates alow resistance high side N-channel MOSFET.Included on the substrate with the listed features are a high performance voltage error amplifier that provides tight voltage regulation accuracy under transient conditions; an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 5.5V; an internally set slow-start circuit to limit inrush currents;and avoltage feed-forward circuit to improve the transient response. Other features include an active high enable, over current protection and thermal shutdown.Toreduce design complexity and external component count, the TPS5430 feedback loop is internally compensated.
The TPS5430 device is available in a thermally enhanced, easy to use 8-pin SOIC PowerPAD™ 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.
