Product Overview

The TPS5430DDA is a 3A 500kHz Step-down Converter with Eco-mode™ 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 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 a voltage feed-forward circuit to improve the transient response. Using the ENA pin, shutdown supply current is reduced to 18µA typically. Other features include an active-high enable, over-current limiting, over-voltage protection and thermal shutdown. To reduce design complexity and external component count, the TPS5430 feedback loop is internally compensated. The TPS5430 regulates a wide variety of power sources including 24V bus.
  • Up to 3A continuous (4A peak) output current
  • High efficiency up to 95% enabled by 110mΩ integrated MOSFET switch
  • Wide output voltage range (adjustable down to 1.22V with 1.5% initial accuracy)
  • Internal compensation minimizes external parts count
  • Improved line regulation and transient response by input voltage feed-forward
  • System protected by over-current limiting, overvoltage protection and thermal shutdown
  • Green product and no Sb/Br
