AP3304W6-7

Overview

The AP3304W6-7 is a multi-mode PWM controller from Diodes Incorporated, designed for high-efficiency offline flyback converters. It features peak current control with QR and CCM modes to optimize performance across load ranges. The device operates at a maximum switching frequency of approximately 100 kHz and includes frequency dithering to reduce EMI radiation. It supports a 60V process and offers comprehensive protection mechanisms including overcurrent, overvoltage, and thermal protection. Packaged in SOT26, it is suitable for open-frame power supplies and USB PD applications.

Feature Summary

Multi-mode operation combining Quasi-Resonant and Continuous Conduction Mode for enhanced efficiency
Integrated frequency dithering to minimize electromagnetic interference emissions
Built-in protection functions including overcurrent, overvoltage, and thermal shutdown

Applications

Open-frame switching power supplies
Power delivery (PD) applications
Mobile phone chargers
Set-top box power supplies

Procurement Notes

Verify the specific suffix W6-7 against the manufacturer's latest datasheet to confirm packaging details and reel specifications. Ensure compatibility with required input voltage ranges and thermal management strategies for the target application. Cross-reference RoHS compliance status with current environmental declarations before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high efficiency under varying load conditions without external feedback complexity. The integrated multi-mode control reduces BOM count compared to discrete solutions. Consider the SOT26 package size constraints and thermal dissipation requirements when laying out the PCB for optimal performance in compact power adapter designs.
