Overview
The AP3987PS-13 is a non-isolated AC/DC converter IC manufactured by Diodes Incorporated, designed as a primary side regulation (PSR) switcher. It operates in an SOIC-8 surface-mount package and utilizes silicon technology. The device delivers up to 15 W of output power with a single output configuration. Key electrical specifications include a quiescent supply current of 550 uA. This component functions as an offline switching regulator for power conversion applications.
Feature Summary
- Integrates primary side regulation to eliminate the need for optocouplers and secondary-side feedback components.
- Features built-in protection mechanisms including over-voltage and surge protection capabilities.
- Designed for high efficiency operation through optimized switching control in flyback topologies.
Applications
- Offline AC/DC power supplies
- Primary side regulated adapter designs
- Flyback converter implementations
Procurement Notes
Verify the specific suffix PS-13 against official Diodes Incorporated documentation to confirm pinout and thermal characteristics. Confirm that the SOIC-8 package variant matches your PCB footprint requirements. Check for any recent product change notifications regarding material or manufacturing site updates before finalizing procurement plans.
Selection Notes
Select this component when designing cost-effective, non-isolated power solutions requiring primary side regulation. Ensure the application supports the specified operating temperature range and voltage limits. Compare performance metrics against alternative PSR controllers if higher power density or different packaging options are required for the target design.
Part Context
This part belongs to the AP3987 series of AC/DC converters from Diodes Incorporated. It is categorized under PMIC - Power Management ICs. The series focuses on providing efficient power conversion for low to medium power applications using simplified control architectures typical of primary side regulation technologies.
Replacement Considerations
The AP3987CTS7-13 is listed as a potential replacement option. Verify compatibility regarding the SO-7 package versus the SOIC-8 package used by the AP3987PS-13. Confirm functional equivalence and pinout alignment before substituting.
