TPS5450 - Step-Down Converter

General Description

The TPS5450 is a high-output-current PWM converter that integrates a low-resistance, high-side N-channel MOSFET.

Key Features

  • Wide input voltage range: 5.5 V to 36 V.
  • Up to 5-A continuous (6-A peak) output current.
  • High efficiency greater than 90% enabled by 110- mΩ integrated MOSFET switch.
  • Wide output voltage range: adjustable down to 1.22 V with 1.5% initial accuracy.
  • Internal compensation minimizes external part count.
  • Fixed 500-kHz switching frequency for small filter size.
  • 18-μA shutdown supply current.
  • Improved line regulation and transient.
