Overview
The BD93941FP-E2 is a four-channel constant current LED driver IC designed for large LCD backlight applications. It utilizes a boost topology to drive white LEDs with an adjustable output voltage and a maximum output current of 200 mA per channel. The device operates within an input voltage range of 9 V to 35 V at a switching frequency of 150 kHz. Packaged in an HSOP-20 format, it supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Four independent constant current channels for uniform LED illumination
- Integrated boost converter topology for high-voltage LED driving
- Supports wide-range analog dimming control
Applications
- Large LCD panel backlighting systems
- White LED array drivers
- Industrial display modules
Procurement Notes
Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm that the HSOP-20 package dimensions align with existing PCB footprints. Ensure supply chain stability given the end-of-life designation. Validate RoHS compliance requirements against specific project regulations. Review the official datasheet for any updates regarding moisture sensitivity levels and handling precautions.
Selection Notes
Select this component when designing for large LCD backlights requiring four distinct LED strings. It is suitable for systems needing a 9 V to 35 V input range and precise current regulation up to 200 mA. Consider the HSOP-20 package constraints during layout. Evaluate thermal performance within the specified operating temperature limits. Compare against single-channel alternatives if fewer outputs are sufficient.
Part Context
This part belongs to the BD93941FP series of LED lighting drivers manufactured by ROHM Semiconductor. It is categorized under LED Lighting Drivers and Driver ICs. The manufacturer identifies it specifically for white LED applications using a boost topology. The product line focuses on providing stable constant current solutions for display technologies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on matching electrical specifications and pin compatibility.
