AS3647-ZWLT-500

Overview

The AS3647-ZWLT-500 is a dual-output DC-DC step-up LED driver IC manufactured by ams-OSRAM. It features I2C dimming control and supports an output current of 800mA for flash applications. The device is housed in a compact 13-WLCSP package with dimensions of 2.25x1.5 mm.

Feature Summary

Dual-output DC-DC regulator architecture
I2C interface for digital dimming control
Step-up (Boost) converter topology

Applications

Mobile device camera flash systems
In-cabin monitoring illumination
Compact automotive lighting modules

Procurement Notes

Verify the specific suffix -500 against official datasheets to confirm current rating or binning differences. Ensure RoHS compliance status matches project requirements. Confirm WLCSP availability through authorized distributors as lead times may vary.

Selection Notes

Select this component for space-constrained designs requiring high-intensity flash output. The I2C interface allows precise brightness control via microcontroller. Evaluate thermal management needs given the small WLCSP footprint and high current capability.

Part Context

This part belongs to the AS3647 family of LED drivers designed for mobile and automotive applications. It integrates power switches and control logic into a single chip, reducing external component count compared to discrete solutions.

Replacement Considerations

Check for pin-compatible alternatives within the same manufacturer's portfolio. Verify electrical parameters such as input voltage range and switching frequency match existing design constraints before substitution.
