AMS4122 - SINGLE 4A/DUAL 2A BUCK CONVERTER

General Description

AMS4122 is a dual switching regulator capable to deliver up to 2A for each channel.

Internally Compensated internal Soft Start makes AMS4122 one of the simplest and easiest switching regulators to use with the minimum external components.

Each regulator has independent hiccup current limit.

Key Features

  • 2 Independent Asynchronous Buck Converters in SO-8.
  • Internally compensated.
  • Built in soft start.
  • Enable with Zero current shut down.
  • 400KHz switching per output.
  • Interleaved oscillator to reduced supply ripple.
  • Simply re-configures to 2 phase single output.
  • Up to 4A output in 2 phase mode.
  • Independent hiccup current limit.
