TPS5430 - 3-A Wide Input Range Step-Down Converter

General 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:.
  • TPS5430: 5.5V to 36V.
  • TPS5431: 5.5V to 23V.
  • 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 compensation minimizes external parts count.
  • Fixed 500kHz switching frequency for small filter size.
  • Improved line regulation and transient res.
