AP3103AKTR-G1

Overview

The AP3103AKTR-G1 is an AC/DC PWM controller from Diodes Incorporated, designed for offline flyback converter topologies. It operates with a switching frequency of 20 kHz and incorporates Leading Edge Blanking (LEB). The device supports an input supply voltage range from 10 V to 25 V and features output overvoltage protection (VOVP) and overload protection (OLP). It is housed in a SOT-26-6 package and functions within a temperature range of -40°C to +150°C.

Feature Summary

• Integrated leading edge blanking for noise immunity
• Built-in output overvoltage and overload protection mechanisms
• Optimized for flyback topology applications

Applications

• Offline power supplies
• AC/DC conversion systems
• General purpose power management circuits

Procurement Notes

Verify the specific suffix 'G1' against the manufacturer's current datasheet to confirm compliance with RoHS directives and lead-free status. Ensure the SOT-26-6 package dimensions match your PCB footprint requirements. Confirm that the humidity sensitivity level aligns with your assembly line storage and reflow soldering profiles before procurement.

Selection Notes

Select this component when designing flyback converters requiring low-frequency operation at 20 kHz. It is suitable for applications needing integrated VOVP and OLP without external circuitry. Consider the wide operating temperature range up to 150°C for high-thermal environments. Verify that the 10 V to 25 V supply range meets the startup and running voltage needs of your design.

Part Context

This part belongs to the AP3103 series of AC/DC controllers by Diodes Incorporated. It is categorized under PMIC and Off-Line Converters. The series focuses on cost-effective solutions for standard power adapters and chargers using silicon technology.

Replacement Considerations

Consult official substitution guides for compatible flyback controllers. Verify pinout compatibility and electrical parameter alignment before replacing.
