FAN5608DHMPX

Overview

The FAN5608DHMPX is a dual-output DC-DC step-up (boost) LED driver IC manufactured by onsemi. It operates within an input voltage range of 2.7 V to 5.5 V and provides regulated output currents up to 20 mA per channel. The device utilizes a boost topology and supports PWM dimming for backlight applications. It is housed in a compact 12-MLP (4x4 mm) surface-mount package, suitable for space-constrained portable electronics.

Feature Summary

• Dual current-regulated outputs for independent LED control
• Integrated step-up DC-DC converter with internal switches
• Supports PWM dimming for brightness adjustment

Applications

• Mobile phone backlight systems
• Portable electronic device illumination
• LCD backlight power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for End-of-Life (EOL) notices or Production Change Notices (PCN) as availability may be restricted. Ensure the MLP-12 package variant matches design requirements before procurement.

Selection Notes

Select this component for designs requiring dual-channel LED driving from a single supply rail. The 2.7 V minimum input voltage allows operation from standard lithium-ion batteries. Verify that the 20 mA output current meets load requirements. The 12-MLP package necessitates specific PCB footprint considerations for thermal and electrical performance.

Part Context

This part belongs to the FAN5608 series of LED drivers from onsemi. It is distinct from the FAN5608DMPX, which lacks the 'H' suffix indicating specific pinout or feature variations. The series targets low-power portable applications requiring efficient boost conversion for LED arrays.
