AS3696-ZQFT

Overview

The AS3696-ZQFT is a four-output LED driver controller manufactured by ams-OSRAM USA INC. Designed for backlight and lighting applications, it integrates a step-up converter and supports PWM dimming. The device operates within a supply voltage range up to 5.5V and functions across an ambient temperature range of -30°C to 85°C. It utilizes a 32-VFQFN exposed pad surface-mount package.

Feature Summary

• Integrates a step-up converter for efficient power management in LED circuits
• Supports Pulse Width Modulation (PWM) dimming for precise brightness control
• Features four independent output channels for multi-zone lighting or backlighting

Applications

• LED backlight systems
• General illumination lighting
• Multi-zone LED arrays

Procurement Notes

Verify the specific suffix ZQFT against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage limits not exceeding 5.5V. Confirm thermal requirements align with the -30°C to 85°C operating range. Cross-reference manufacturer part numbers to avoid confusion with similar variants like AS3696-ZQFM.

Selection Notes

Select this component when designing circuits requiring integrated boost conversion and multi-channel PWM control. It is suitable for space-constrained designs due to its compact QFN package. Evaluate thermal dissipation capabilities relative to the exposed pad design. Ensure the application does not exceed the maximum specified ambient temperature limits.

Part Context

This component belongs to the AS3696 series of LED driver controllers from ams-OSRAM. The series targets high-efficiency lighting solutions. The ZQFT designation typically indicates a specific packaging configuration optimized for automated surface-mount assembly processes.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify that substitute components support identical PWM dimming frequencies and output current capabilities.
