Overview
The AP3970P-G1 is a primary side power switcher designed for off-line Switched Mode Power Supplies (SMPS). It operates within an input voltage range of 4.5 V to 15 V and provides a maximum output voltage of 5 V. The device functions reliably across a temperature range from -40°C to +85°C. Packaged in an 8-pin DIP configuration, it serves as a low-cost solution for offline power applications.
Feature Summary
- Primary side power switching architecture for off-line SMPS topologies
- Designed for low total cost solutions in offline power conversion
- Operates with wide input voltage tolerance suitable for various supply conditions
Applications
- Off-line Switched Mode Power Supplies
- Low cost AC-DC adapter designs
- Offline power conversion systems
Procurement Notes
Verify the specific package type against your board design requirements, as datasheet references indicate both DIP and SMD variants exist within the product family. Confirm that the 8-pin DIP form factor matches your assembly process. Ensure compatibility with the intended off-line SMPS topology before finalizing procurement decisions.
Selection Notes
Select this component when a primary side regulated solution is required for offline applications. It is suitable for designs prioritizing cost efficiency over high precision regulation. Verify that the 8-pin DIP package fits the mechanical constraints and that the operating temperature range meets environmental specifications.
Part Context
Manufactured by Diodes Incorporated, the AP3970 series addresses the need for economical power management in offline environments. This specific part number denotes the DIP-8 variant, distinguishing it from surface mount options. It belongs to the specialized PMIC category focused on simple, robust switching control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-references based on pinout compatibility and electrical specifications only if official substitution data is obtained from the manufacturer.
