AP5726FDCG-7

LED Driver IC Overview

The AP5726FDCG-7 is a white LED step-up DC/DC converter from Diodes Incorporated, designed for driving 2 to 6 series-connected LEDs. It operates within an input voltage range of 2.7 V to 5.5 V and delivers a regulated output current up to 750 mA. The device functions at a switching frequency of 1.2 MHz and supports adjustable output voltage. It features soft start functionality and operates across a temperature range of -40°C to +85°C. Packaged in a compact 6-UDFN (U-DFN2020-6) surface-mount package, it integrates protection mechanisms suitable for portable lighting applications.

LED Driver IC Procurement Notes

Verify the specific suffix 'FDCG' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad configuration. Ensure the ordering quantity aligns with the standard factory packaging requirements specified by Diodes Incorporated. Cross-reference the RoHS compliance status with the latest product change notices before finalizing procurement specifications.

LED Driver IC Selection Notes

Select this component when designing circuits requiring a single-channel boost driver for 2 to 6 series LEDs within a 5.5 V maximum input constraint. The 750 mA current rating suits high-brightness applications, while the 1.2 MHz frequency allows for small inductors. Consider the U-DFN2020-6 package dimensions for strict space-constrained PCB layouts compared to larger packages.

LED Driver IC Part Context

This part belongs to the AP5726 series of LED lighting drivers manufactured by Diodes Incorporated. The series focuses on efficient power management for portable electronics. The AP5726FDCG-7 variant specifically utilizes the FDCG marking code and U-DFN2020-6 package style, distinguishing it from other pinouts or thermal options within the broader family.

LED Driver IC Replacement Considerations

Check for AP5725 variants if lower current requirements exist, though topology may differ. Verify direct substitutes only through Diodes Incorporated's official cross-reference tools. Do not assume functional equivalence with generic boost converters without validating control loop stability and LED drive characteristics.
