Description

The TPS543x is a high-output-current PWM converter that integrates a low-resistance, high-side N-channel MOSFET.

Key Features

  • Wide input voltage range
  • Up to 3A continuous (4A peak) output current
  • High efficiency up to 95% enabled by 100mΩ integrated MOSFET switch
  • Wide output voltage range: adjustable down to 1.22V with 1.5% initial accuracy
  • Internal pensation minimizes external parts count
  • Fixed 500kHz switching frequency for small filter size
  • Improved line regulation and transient response by input voltage feedforward
  • System protected by overcurrent limiting, overvoltage protection, and thermal shutdown
  • 40°C to 125°C operating junction temperature range
  • Available in small thermally enhanced 8-pin SO PowerPAD™ integrated circuit package
