AP3105VKTR-G1

Overview

The AP3105VKTR-G1 is a Green PWM controller designed for offline flyback AC/DC conversion applications. It operates with a peak current mode control architecture to optimize efficiency and reduce electromagnetic interference. The device integrates high-voltage startup circuitry, eliminating the need for auxiliary winding resistors. Key electrical specifications include a maximum switching frequency of 65 kHz, a supply voltage range of 12V to 30V, and a peak drain current capability of 350mA. It features cycle-by-cycle current limiting and thermal shutdown protection.

Feature Summary

• Integrates high-voltage startup circuitry to minimize external component count
• Implements peak current mode control for improved line and load regulation
• Includes built-in thermal shutdown and cycle-by-cycle current limiting for robust operation

Applications

• Offline flyback power supplies
• Adapter and charger designs
• General-purpose AC/DC conversion systems

Procurement Notes

Verify the specific suffix 'VKTR' against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status via the official Diodes Incorporated product compliance documentation. Check for any recent Product Change Notifications (PCN) that may affect assembly or testing sites. Ensure the ordering part number matches the exact voltage and current ratings required for the target application design.

Selection Notes

Select this component for cost-sensitive offline power supplies requiring simplified bill of materials due to integrated startup circuits. Consider its 350mA peak current limit when designing transformer parameters for low-power applications. Evaluate the fixed 65kHz switching frequency against EMI filter requirements. Compare performance metrics with other members of the AP3105 family if variable frequency or different current limits are needed.

Part Context

This component belongs to the AP3105 series of Green PWM controllers from Diodes Incorporated. The series focuses on reducing standby power consumption in offline converters. The 'G1' suffix indicates RoHS compliance and green manufacturing processes. The VKTR suffix typically denotes the specific tape-and-reel packaging configuration for surface-mount assembly.
