Overview
The AP3127HCMKTR-G1 is an AC/DC converter and PWM controller manufactured by Diodes Incorporated, designed for offline flyback topologies. It operates with a fixed switching frequency of 100 kHz and supports a VCC supply voltage range of 10V to 28V. The device features a startup voltage of 15.8V and includes comprehensive protection mechanisms such as current limiting, overvoltage protection, and overload protection. Packaged in a SOT-26 surface-mount format, it is rated for junction temperatures between -40°C and 150°C. This component is currently marked as obsolete by the manufacturer.
Feature Summary
- Optimized for high-efficiency power conversion in consumer portable products through integrated pulse width modulation control.
- Incorporates energy-saving modes that utilize frequency folding during medium load conditions to enhance system efficiency.
- Provides robust circuit protection via built-in current limiting, overvoltage, and overload safeguards.
Applications
- Smartphone chargers
- Notebook computer power adapters
- Set-top boxes
- Gaming consoles
- Network equipment
Procurement Notes
Verify end-of-life status before design finalization, as the AP3127HCMKTR-G1 is officially discontinued by Diodes Incorporated. Confirm availability of alternative sources or substitute components for production continuity. Ensure compatibility with existing PCB footprints if transitioning from active inventory. Review latest product change notifications for any historical specification updates prior to implementation.
Selection Notes
Select this component for cost-sensitive applications requiring reliable offline power management in compact form factors. The SOT-26 package suits space-constrained designs. Consider the fixed 100 kHz switching frequency when designing magnetic components. Evaluate thermal performance within the specified -40°C to 150°C junction temperature range for long-term reliability in enclosed enclosures.
Part Context
This part belongs to the AP3127 series of AC/DC converters from Diodes Incorporated, engineered specifically for consumer electronics power supplies. The series targets markets demanding high efficiency and low standby power consumption. As an obsolete item, it represents a legacy solution previously utilized in widespread portable device charging infrastructure and general-purpose adapter designs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Diodes Incorporated for current portfolio alternatives compatible with similar flyback controller specifications.
