ADP1108 - DC-to-DC Converter

General Description

The ADP1108 is a highly versatile micropower switch-mode dc-dc converter that operates from an input voltage supply as low as 2.0 V and typically starts up from 1.8 V.

The ADP1108 can be programmed into a step-up or step-down dc-to-dc converter with only three external components.

Key Features

  • Operates at Supply Voltages From 2.0 V to 30 V Consumes Only 110 ␮A Supply Current Step-Up or Step-Down Mode Operation Minimum External Components Required Low Battery Detector Comparator On-Chip User-Adjustable Current Limit Internal 1 A Power Switch Fixed or Adjustable Output Voltage Versions 8-Pin DIP or SO-8 Package.
