FAN5616MPX

Overview

The FAN5616MPX is a high-performance constant current LED driver manufactured by onsemi. It features three independent output channels, each capable of delivering up to 40 mA of drive current. The device supports a maximum output voltage of 6 V and incorporates an internal switching mechanism for efficient power management. Designed for surface-mount applications, it utilizes a 16-lead MLP (Mini Leadframe Package) with an exposed pad for enhanced thermal dissipation. The component accepts PWM dimming signals for precise brightness control and includes regulation capabilities to maintain consistent LED performance across varying conditions.

Feature Summary

• Three independent constant current output channels for multi-LED configurations
• Supports Pulse Width Modulation (PWM) dimming for precise brightness adjustment
• Integrated internal switches eliminate the need for external components
• Surface-mount design with exposed pad for improved thermal performance

Applications

• Display backlight systems
• Portable electronic devices requiring compact LED drivers
• Industrial indicator lighting circuits

Procurement Notes

Verify the specific package variant and revision code against the manufacturer's latest datasheet before procurement. Confirm that the 16-MLP footprint matches your PCB layout requirements. Ensure compatibility with the intended PWM dimming frequency range. Check for any end-of-life notices or recommended alternative part numbers if long-term supply stability is required for the production cycle.

Selection Notes

Select this component when a compact, multi-channel LED driver is needed for low-current applications. The 40 mA per channel rating suits standard indicator LEDs or small display segments. Consider the MLP package size constraints and thermal management needs. Verify that the 6 V output voltage limit aligns with the forward voltage requirements of the connected LED array. Ensure the system supports PWM dimming signals for the desired control interface.
