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 µA 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 tools to aid in achieving high-performance power supply designs to meet aggressive equipment development cycles.
