Overview
The iW7038-00-QFN4 is a 16-channel internal current sink LED backlighting driver designed for high dynamic range (HDR) LCD displays. It integrates precision current sinks with advanced digital control technology to enhance brightness regulation. The device operates as a standalone unit, requiring no microcontroller, and supports configurable output currents ranging from 20mA to 150mA via external resistors.
Feature Summary
- Integrates 16 high-precision internal current sinks for uniform LED driving
- Utilizes advanced digital control technology to improve brightness accuracy
- Operates as a standalone driver without requiring an external microcontroller
Applications
- High Dynamic Range (HDR) LCD televisions
- LCD computer monitors
- High-end display backlighting systems
Procurement Notes
Verify the specific suffix QFN4 against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm lifecycle status as restricted before finalizing design-in decisions. Ensure external resistor values match the required 20mA to 150mA configuration range specified in the datasheet.
Selection Notes
Select this component when designing HDR LCD backlights requiring precise current matching across multiple channels. It is suitable for applications needing standalone operation without MCU overhead. Consider the 16-channel capacity for large panel sizes and verify thermal performance within the QFN4 footprint constraints.
Part Context
This part belongs to Renesas' iW series of LED lighting drivers. It complements other backlight solutions by offering integrated current sinking capabilities. The product line focuses on improving display quality through precise digital control and simplified system architecture for consumer electronics manufacturers.
Replacement Considerations
Check Renesas official substitution lists for equivalent 16-channel LED drivers. Verify pin-to-pin compatibility if replacing legacy parts. Ensure new alternatives support the same HDR brightness control requirements and standalone operating mode.
