BD93942F-GE2

Overview

The BD93942F-GE2 is a DC/DC converter type white LED driver IC designed for large screen applications. It features a boost topology with four independent constant current outputs, each capable of delivering up to 150mA. The device operates within an input voltage range of 9V to 35V and supports a switching frequency of 150kHz. It includes adjustable feedback voltage for precise current setting and offers analog dimming capabilities. The component is housed in a SOP16 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

Four-channel constant current driver with individual LED detection for open and short circuit protection
Built-in overvoltage protection and reduced voltage protection circuits for enhanced safety
Supports analog linear dimming via the ADIM pin for brightness control
Integrated FET gate drive with 5.8V swing and built-in Vout discharge circuit for shutdown

Applications

White LED drivers for large LCD panels
Backlighting systems for large display screens
Industrial lighting applications requiring multi-channel constant current drive

Procurement Notes

Verify the specific suffix GE2 to ensure correct packaging and RoHS compliance status. Confirm that the NRND (Not Recommended for New Designs) status aligns with long-term supply requirements. Check datasheet revisions for any updates to electrical characteristics or thermal parameters before finalizing procurement specifications.

Selection Notes

Select this component when designing for large displays requiring four independent LED channels with high accuracy. Ensure the application input voltage falls within the 9V to 35V range. Consider the SOP16 package size constraints and verify that the 150mA per channel output meets the total luminous flux requirements of the target display panel.

Part Context

This part belongs to ROHM's series of DC/DC type white LED drivers optimized for large screen applications. It integrates power switching and control logic into a single package to reduce external component count. The family focuses on providing stable constant current regulation with advanced protection features suitable for demanding display backlighting environments.
