Overview
The FAN5606DMPX is a serial LED driver IC featuring an integrated boost DC/DC converter. It regulates output current from a battery source with an input voltage range of 2.7V to 5.5V. The device provides one regulated output channel capable of delivering up to 20mA. It operates at a switching frequency of 500kHz and supports both analog and PWM dimming methods. The component utilizes an internal switch within an 8-MLP (3x3) surface-mount package.
Feature Summary
- Integrates a step-up DC/DC converter for generating stable LED currents from varying battery voltages
- Supports dual dimming control via analog signals and pulse-width modulation inputs
- Contains an internal power switch to minimize external component count
- Designed for serial connection configurations in backlight applications
Applications
- LED backlighting systems
- Portable electronic devices requiring battery-powered LED drivers
- Serial LED string regulation circuits
Procurement Notes
Verify the specific suffix DMPX against the manufacturer datasheet to confirm pinout and thermal pad configuration. Confirm end-of-life status as distribution records indicate this part may be discontinued. Ensure compatibility with existing PCB footprints for the 8-MLP package before procurement.
Selection Notes
Select this component for designs requiring a single-channel, high-efficiency boost driver for serial LEDs. It is suitable for applications where input voltage fluctuates between 2.7V and 5.5V. Consider the 8-MLP package size constraints and the requirement for both analog and PWM dimming interfaces when evaluating alternatives.
Part Context
The FAN5606 series belongs to onsemi's portfolio of power management ICs focused on LED illumination. This specific model integrates the boost converter and driver into a single compact solution, reducing the bill of materials for portable backlighting designs compared to discrete implementations.
Replacement Considerations
Public records indicate the FAN5606DMPX is discontinued. Verify if the FAN5606DMPXTR or other suffix variants are available as direct replacements. Consult the manufacturer for current lifecycle status and recommended substitute components.
