Overview
The ADP1073AN is a micropower DC-DC converter from Analog Devices, designed for step-up or step-down operation with an input voltage range of 1.0 V to 30 V. It features an internal 1 A power switch and operates in both boost and buck modes. The device includes a low battery detector and user-adjustable current limit. Available in an 8-Lead DIP package, it supports fixed output voltages of 3.3 V, 5 V, and 12 V, as well as adjustable configurations.
Feature Summary
- Operates in step-up or step-down mode with input supply from 1.0 V to 30 V
- Integrates an internal 1 A power switch requiring few external components
- Includes a low battery detector and on-chip user-adjustable current limit
Applications
- Single-cell to 5 V converters
- Laptop and palmtop computers
- Battery backup supplies
- Cellular telephones
- Portable instruments
Procurement Notes
Verify the specific suffix 'AN' against official datasheets to confirm the 8-Lead DIP package configuration. Confirm availability status as older component families may have limited stock or discontinuation notices. Ensure compatibility with required fixed or adjustable output voltage versions before procurement.
Selection Notes
Select this component for applications requiring a single-cell battery source or wide input voltage ranges. Choose the fixed voltage version for simplified design or the adjustable variant for custom output requirements. Consider the DIP package for through-hole mounting needs in portable or industrial instrumentation designs.
Part Context
The ADP1073 belongs to a family of micropower switching regulators optimized for low input voltage operation. It serves as a versatile solution for converting single-cell battery power to standard logic levels like 5 V or 3.3 V. The series supports both step-up and step-down topologies within a compact footprint.
Replacement Considerations
Check for direct replacements such as the ADP1073AR (SOIC) if surface mount is preferred. Verify pinout compatibility and thermal performance when substituting packages. Consult manufacturer obsolescence notices for long-term supply chain stability.
