AS3648-ZWLT-500

Overview

The AS3648-ZWLT-500 is a high-performance LED driver IC manufactured by ams OSRAM. It features two independent outputs and operates as a DC-DC step-up regulator. The device supports I2C dimming for precise control. It is housed in a compact 13WLCSP package, designed for space-constrained applications requiring efficient light regulation.

Feature Summary

• Integrates dual output channels for flexible LED configuration
• Utilizes I2C interface for digital dimming and control
• Functions as a boost converter for efficient power management

Applications

• Near-to-eye display systems
• Augmented reality (AR) devices
• Virtual reality (VR) headsets

Procurement Notes

Verify the specific suffix and packaging variant against official datasheets before ordering. Confirm compatibility with system voltage requirements and I2C bus speeds. Ensure the selected package matches the PCB footprint specifications to avoid assembly issues.

Selection Notes

Select this component for applications requiring integrated boost regulation and digital control in minimal space. Consider the thermal performance of the WLCSP package and the need for external inductors typical in boost converter designs. Evaluate the I2C addressability if multiple drivers are used on the same bus.

Part Context

This part belongs to the AS364x series of LED drivers from ams OSRAM, which are optimized for consumer electronics and wearable technology. The series focuses on providing high efficiency and small form factors suitable for portable devices where battery life and size are critical constraints.

Replacement Considerations

Check for direct pin-compatible alternatives within the AS364x family. Verify that any substitute maintains the same I2C protocol support and output current capabilities. Ensure the replacement package matches the existing board layout.
