FAN5608DMPX

Overview

The FAN5608DMPX is a boost LED driver IC from onsemi, designed for portable applications. It operates with an input voltage range of 2.7 V to 5.5 V and supports a maximum power supply voltage of 5.5 V. The device features a boost topology and is housed in an MLP-12 package (8-MLP 3x3). It functions as a serial/parallel LED driver with PWM regulation capability. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Utilizes an inductive boost architecture for efficient LED current regulation
• Supports PWM dimming control for brightness adjustment
• Designed specifically for portable application constraints

Applications

• Portable electronic devices requiring LED illumination
• LED lighting driver circuits using boost topology
• Battery-powered systems needing regulated LED current

Procurement Notes

Verify the specific package variant, as datasheets may list MLP-12 while distributors specify 8-MLP. Confirm end-of-life status if sourcing for new designs, as some listings indicate obsolescence. Ensure compatibility with existing PCB footprints by checking pin definitions against the official onsemi datasheet rather than relying solely on distributor descriptions.

Selection Notes

Select this component when a compact boost regulator is required for low-power LED strings in portable electronics. Consider the input voltage range relative to the battery source. Evaluate thermal performance within the MLP-12 package for the intended ambient temperature conditions. Verify that the PWM control interface matches the system controller capabilities.
