AL3066S16-13

Overview

The AL3066S16-13 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 voltages up to 100 V. The device delivers a maximum output current of 250 mA per channel with a switching frequency adjustable between 100 kHz and 1 MHz. Designed for surface-mount applications, it utilizes an SOIC-16 package and functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Four independent constant current channels for multi-string LED backlighting
• Integrated PWM dimming capability for precise brightness control
• Open LED protection circuitry to prevent damage during fault conditions

Applications

• LCD panel backlight drivers
• LED lighting modules
• Portable electronic displays

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm the specific suffix matches the required package and tape-and-reel specifications. Check for end-of-life status as some listings indicate obsolescence. Ensure RoHS compliance documentation aligns with regional regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when designing high-density LED backlight systems requiring four independent current paths. The boost topology suits applications where the LED string voltage exceeds the supply rail. Evaluate thermal performance in the SOIC-16 package against system power dissipation limits. Ensure the external inductor and capacitor values support the desired 100 kHz to 1 MHz operating frequency range.

Part Context

This part belongs to the AL30 series of LED drivers from Diodes Incorporated. It shares functional similarities with other members like the AL3065 but offers distinct channel configurations. The series targets cost-sensitive consumer electronics markets. Designers often compare it against competitors in the single-channel or dual-channel boost driver categories for space-constrained PCB layouts.

Replacement Considerations
