Overview
The AP3988MTR-G1 is an integrated offline switch designed for flyback topology AC/DC converters. It features a built-in 700V power switch and operates with a fixed switching frequency of 60kHz. The device supports a supply voltage range from 5.8V to 25V, with a startup voltage of 15V. It delivers up to 5.5W of output power and includes internal protection mechanisms against over-temperature, over-voltage, and short-circuit conditions. The component is housed in a 7-SOIC package with seven leads.
Feature Summary
- Integrates a high-voltage power switch for compact offline converter designs
- Includes comprehensive fault protection for enhanced system reliability
- Operates at a fixed frequency to simplify magnetic component design
Applications
- Offline flyback power supplies
- AC/DC converter modules
- General purpose isolated power conversion
Procurement Notes
Verify end-of-life status before finalizing designs, as the manufacturer has announced discontinuation. Confirm current inventory availability through authorized distributors, as stock may be limited or exhausted. Ensure compliance with RoHS3 and REACH regulations if required by your specific application standards. Review the latest datasheet for any potential assembly or test site changes that may affect part characteristics.
Selection Notes
Select this component for low-power applications requiring integrated switching capabilities without external driver circuits. Consider the 700V breakdown voltage for primary-side isolation requirements. Evaluate the 60kHz operating frequency against transformer size constraints. Verify that the 5.5W power limit meets the target load requirements. Check thermal performance within the specified operating temperature range.
Part Context
This part belongs to the AP3988 series of offline switches manufactured by Diodes Incorporated. It is categorized under PMIC AC/DC converters and offline conversion switches. The product line targets cost-effective solutions for small form factor power adapters and chargers.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative components must be selected based on functional equivalence rather than direct cross-reference data.
