Overview
The IW7039S-00-QFN4 is a 32-channel internal current sink LED backlighting driver manufactured by Renesas Electronics. It integrates boost and buck topologies to drive LED arrays with an adjustable output voltage. The device operates on a power supply ranging from 300 mV to 20 V, delivering up to 66 mA per channel. It supports a switching frequency between 44 Hz and 32 kHz. The component functions within an operating temperature range of -20°C to +85°C and is supplied in cut tape or reel packaging.
Feature Summary
- Integrates 32 independent channels for high-density LED control
- Combines boost and buck converter topologies for flexible LED driving
- Features internal current sinks for precise channel regulation
Applications
- LED backlighting drivers
- High-density LED array control systems
Procurement Notes
Verify the specific suffix 'S' against official Renesas documentation to confirm functional differences from standard variants. Confirm availability status as distribution listings may indicate limited stock or special order requirements. Ensure the QFN4 package type matches the target PCB footprint design constraints before finalizing procurement.
Selection Notes
Select this component when designing systems requiring simultaneous control of up to 32 LED channels. The integrated boost and buck capabilities allow for efficient power management across varying LED forward voltage drops. Consider the 66 mA output limit per channel and the specified operating temperature range to ensure compatibility with the thermal environment of the target application.
Part Context
This part belongs to the IW7039 series of LED lighting driver ICs produced by Renesas Electronics. The series is designed for applications requiring multiple synchronized LED outputs. The IW7039S variant specifically denotes the QFN4 package configuration, distinguishing it from other physical form factors available within the same functional family.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Verify that any alternative component maintains identical 32-channel architecture and compatible boost/buck topology specifications.
