Overview

Description

The RTKA211403DE0000BU and RTKA211405DE0000BU boards are used to evaluate the RAA211403 and RAA211405 respectively. They are DC/DC ultra-low Iq (5µA and below), 7V to 40V input standard buck regulators with 300mA of continuous load capability at either fixed 3.3V or 5V output.

Features

  • Simple and low BOM count design
  • 7V to 40V VIN range
  • Output voltage: 5 V
  • Ultra-low 4µA quiescent current during no-load operation and switching
  • Variable switching frequency depending on choke and loading

Applications
