5A, Wide Input Step Down SWIFT Converter

As a member of the SWIFT? family of DC/DC Regulators the TPS5450 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 are 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 A typically. Other features include an active-high enable, overcurrent limiting, overvoltage protection and thermal shutdown. To reduce design complexity and external component count, the TPS5450 feedback loop is internally compensated.
The TPS5450 device is available in a thermally enhanced, 8-pin SOIC PowerPAD? package. TI provides evaluation modules and software tool to aid in achieving high-performance power supply designs to meet aggressive equipment development cycles.
