Overview
The FAN73402MX is a boost switch controller designed for LED backlight driving applications. It operates with a supply voltage range of 10 V to 35 V and delivers an output current capability of 250 mA. The device supports both PWM and analog dimming functions, which can be implemented independently. It features internal soft-start functionality to prevent inrush current during startup. The component is housed in a 16-SOIC surface-mount package and is rated for an operating temperature range of -40°C to 125°C.
Feature Summary
- Supports independent PWM and analog dimming control
- Integrates internal soft-start to limit inrush current
- Designed specifically for LED backlight boost switching
Applications
- LED backlight driving systems
- Display illumination circuits
- Boost converter topologies for lighting
Procurement Notes
Verify the specific suffix and package variant against the official onsemi datasheet to ensure compatibility with your design requirements. Confirm that the 16-SOIC footprint matches your PCB layout. Check for any end-of-life notices or alternative recommendations from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when designing LED backlight drivers requiring integrated boost switching capabilities. Ensure the input voltage stays within the 10 V to 35 V range. Consider the 250 mA output current limit when sizing external components. Verify thermal management needs for the SOIC-16 package under maximum load conditions.
Part Context
This part belongs to the FAN7340 series of LED backlight controllers. It is distinct from other FAN73xx series devices like the FAN7371 gate driver or the standard FAN7340, which may have different pinouts or functionalities. It is manufactured by onsemi using silicon technology for power management ICs.
Replacement Considerations
Consult the official onsemi documentation for direct replacements or pin-compatible alternatives. No public substitute part numbers are confirmed in the provided source material.
