AL3065AS16-13

Overview

The AL3065AS16-13 is a four-channel current source boost LED driver manufactured by Diodes Incorporated. It operates within an input voltage range of 4.5 V to 33 V and supports output currents up to 250 mA per channel. The device features a switching frequency between 100 kHz and 1 MHz, with a maximum output voltage of 60 V. Designed for surface-mount applications in SOIC-16 packages, it functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Integrates four independent high-precision current sources for uniform LED brightness control
• Supports analog and PWM dimming methods for flexible brightness adjustment
• Includes open LED protection to prevent damage during fault conditions

Applications

• LED backlighting for laptop displays
• LED backlighting for television screens
• General-purpose LED lighting systems requiring multi-channel drive

Procurement Notes

Verify the specific suffix 'S16' confirms the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 4.5 V to 33 V input range and thermal requirements for the intended operating environment.

Selection Notes

Select this component for designs requiring four synchronized LED channels driven by a single boost controller. It is suitable for space-constrained portable electronics where low quiescent current and precise current matching are critical. Consider the SOIC-16 footprint constraints and thermal dissipation capabilities during PCB layout planning.

Part Context

This part belongs to the AL30 series of LED drivers from Diodes Incorporated. It is specifically engineered as a boost controller optimized for driving multiple LEDs in series or parallel configurations. The device integrates essential protection features and dimming interfaces commonly required in consumer electronics display backlights.

Replacement Considerations

Check datasheets for cross-reference parts like the AL3066S16-13, which shares similar four-channel boost architecture. Verify pinout compatibility and electrical parameter overlaps before substitution. Ensure any alternative maintains the same package type and dimming interface support.
