TPS54310-Q1 描述

As a member of the SWIFT™ family of dc/dc regulators, the TPS5430 is a high-output-current pulse-width modulation (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 (UVLO) 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 enable (ENA) pin, shutdown supply current is reduced to 18 µA typically. Other features include an active-high enable, overcurrent limiting, overvoltage protection (OVP) and thermal shutdown.
