AP3705KTR-G1

Overview

The AP3705KTR-G1 is a non-isolated flyback AC/DC converter IC manufactured by Diodes Incorporated. It integrates an internal high-voltage switch and operates with a startup voltage of 19.5 V and a supply voltage of 8 V. The device features fault protection mechanisms including over-temperature and short-circuit safeguards, along with soft-start control features to ensure stable operation during power-up sequences.

Feature Summary

• Integrates an internal high-voltage switch for compact design
• Provides over-temperature and short-circuit fault protection
• Includes soft-start functionality for controlled power-up

Applications

• Non-isolated flyback power supply designs
• AC/DC conversion circuits requiring integrated switching
• Applications necessitating built-in thermal and short-circuit protection

Procurement Notes

Verify the specific datasheet version and package details (SOT-23-6) against your schematic requirements. Confirm that the 19.5 V startup threshold and 8 V supply voltage align with your system's biasing capabilities. Ensure compatibility with non-isolated flyback topologies before finalizing procurement decisions.

Selection Notes

Select this component when a non-isolated flyback topology is required with integrated switching capabilities. Consider the 19.5 V startup voltage and 8 V operating supply constraints. Evaluate the need for internal over-temperature and short-circuit protection features in your specific application environment.

Part Context

This part belongs to the Diodes Incorporated PMIC - LED Drivers category, specifically functioning as an AC/DC converter. It is distinct from other series like AP3105 or AP3407 which serve different converter types such as Green PWM or synchronous buck converters respectively.
