Product Overview

The TPS5420D is a High-output-current PWM Converter integrates a low resistance high side N-channel MOSFET. Included on the substrate with the listed features is 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, overvoltage protection and thermal shutdown. To reduce design complexity and external component count, the TPS5420 feedback loop is internally compensated.
  • Up to 2A continuous (3A 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
  • Fixed 500kHz switching frequency for small filter size
  • Improved line regulation and transient response by input voltage feed forward
  • System protected by overcurrent limiting, over voltage protection and thermal shutdown
  • Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
