AL5836QT14-13

Overview

The AL5836QT14-13 is a three-channel linear LED driver IC manufactured by Diodes Incorporated. It operates within an input voltage range of 3.5 V to 50 V and provides a regulated output current of 50 mA per channel. The device supports PWM dimming for brightness control and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a TSSOP-14 surface-mount format, it integrates high-voltage power switches suitable for compact lighting applications.

Feature Summary

• Integrates three independent linear driver channels with integrated high-voltage power switches
• Supports precise pulse-width modulation (PWM) dimming for adjustable LED brightness
• Operates with a wide input voltage range up to 50 V for flexible system design

Applications

• LED backlighting modules requiring multi-zone control
• General solid-state lighting fixtures
• Compact LED driver circuits with space constraints

Procurement Notes

Verify the specific suffix QT14-13 against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the TSSOP-14 package. Cross-reference RoHS compliance status directly with the supplier documentation prior to integration into final assemblies.

Selection Notes

Select this component when a multi-channel solution is required without external switching components. The linear topology simplifies design but requires thermal management considerations due to power dissipation. Verify that the load voltage drop remains within the 50 V supply limit and that the 50 mA current rating matches the LED string requirements.

Part Context

This part belongs to the AL5836 series of LED lighting drivers from Diodes Incorporated. It is designed as a cost-effective alternative to complex switching regulators for low-to-medium power LED applications. The TSSOP-14 package allows for efficient board space utilization compared to larger through-hole alternatives.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the three-channel configuration, 50 mA output capability, and TSSOP-14 pinout compatibility.
