Product Overview


The TPS5450DDARG4 is a 5A 500kHz Step-down 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 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 TPS5450 feedback loop is internally compensated.
  • Up to 5A continuous (6A peak) output current
  • High efficiency greater than 90% 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
  • 18µA Shutdown supply current
  • 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

Applications

Power Management; Consumer Electronics
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
