Overview
The ADP1108AN-12 is a micropower DC/DC converter manufactured by Analog Devices Inc. It supports step-up, step-down, and inverting topologies with an input voltage range of 2V to 30V. The device delivers a fixed output voltage of 12V at a maximum current of 0.4A. Designed for minimal external component requirements, it operates efficiently within a supply voltage range of 2V to 12V for boost applications and up to 30V for buck configurations.
Feature Summary
- Supports versatile conversion modes including step-up, step-down, and inverting operations
- Requires only four external components for fixed output configuration
- Operates effectively across wide input voltage ranges for diverse power scenarios
Applications
- Portable instrumentation requiring compact power solutions
- Battery-powered systems needing efficient voltage regulation
- Industrial control circuits utilizing micropower converters
Procurement Notes
Verify the specific suffix 'AN' against official Analog Devices documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure the ordering part number matches the exact electrical specifications required for the target application design.
Selection Notes
Select this component when a fixed 12V output is required from varying input sources. Consider the 0.4A output current limit and the need for only four external passive components. Evaluate the operating temperature range and package constraints against the system's thermal and spatial requirements before finalizing the design.
Part Context
This part belongs to the LT1108 family of micropower DC/DC converters. The family is characterized by its ability to function in multiple topologies using minimal external circuitry. The ADP1108 variant specifically targets applications requiring stable fixed voltage outputs from low-voltage sources.
Replacement Considerations
LT1108CS8-12: Verified equivalent offering identical 12V output and topology support in SOIC-8 package. LT1108CN8-12: Verified equivalent providing 12V output in PDIP-8 package. Verify pinout compatibility and thermal performance differences between packages.
