Overview
The ADP1108AR-12 is a micropower DC-to-DC switching regulator manufactured by Analog Devices Inc. It operates from input supply voltages ranging from 2.0 V to 30 V, supporting both step-up and step-down configurations. The device delivers a fixed output voltage of 12 V with an internal power switch capable of handling up to 1 A. It consumes only 110 µA of supply current during operation. The component is housed in an 8-pin SOIC package.
Feature Summary
- Versatile topology supporting step-up, step-down, and inverting converter applications
- Integrated 1 A internal power switch for simplified design
- Low quiescent supply current of 110 µA for energy efficiency
- Requires minimal external components to achieve fixed or adjustable output
Applications
- Portable instruments and handheld devices
- LCD bias generators
- Battery backup supplies
- Cellular telephones and mobile peripherals
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Ensure the operating environment remains within the specified temperature range. Confirm that the required output current does not exceed the internal switch limits under all load conditions.
Selection Notes
Select this component when designing systems requiring a compact solution for converting varying battery voltages to stable rails. It is suitable for applications where low standby current is critical. Consider the fixed 12 V output constraint and ensure the input voltage range aligns with the source supply capabilities.
Part Context
This part belongs to the ADP1108 family of micropower DC/DC converters. The family includes variants with different fixed output voltages (such as 5 V) and adjustable versions. These regulators are designed to replace linear regulators in battery-powered systems to extend operational life through higher conversion efficiency.
Replacement Considerations
Direct replacements include other ADP1108 variants with compatible packaging. Verify that substitute parts maintain the same 1 A switch current rating and 110 µA quiescent current specifications to ensure equivalent performance.
