Overview
The ISL78100ARZ-TK is a high-power LED driver IC from the Renesas ISL78100 series, designed for automotive-grade applications. It integrates boost and buck topologies to drive high-power LEDs with an output current of 1 A. The device operates on a supply voltage range of 2.7 V to 16 V and supports a switching frequency of 1 MHz. It features PWM dimming capabilities along with short circuit and thermal protection mechanisms. The component is housed in a QFN-20 package (HVQCCN) and functions within a temperature range of -40°C to +105°C.
Feature Summary
- Integrates boost and buck converter topologies for flexible high-power LED driving
- Supports precise PWM dimming control for brightness adjustment
- Includes built-in short circuit and thermal protection for system reliability
Applications
- Automotive exterior lighting systems
- High-power LED illumination modules
- LED display drivers requiring high current output
Procurement Notes
Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging specifications and ensure compatibility with automated assembly processes. Confirm that the QFN-20 package dimensions match the target PCB footprint design requirements. Check for any updated moisture sensitivity level classifications prior to soldering.
Selection Notes
Select this component when a single-channel driver capable of handling both boost and buck operations is required for high-power LED applications. Ensure the input voltage range of 2.7 V to 16 V aligns with the system power supply. Consider the 1 A output current capability and the need for PWM dimming functionality in the final design.
Part Context
This part belongs to the ISL78100 series of high-power LED drivers manufactured by Renesas Electronics Corporation (formerly Intersil). The series is characterized by its ability to drive high-power LEDs efficiently using integrated power switches. The ISL78100ARZ variant represents the standard commercial/automotive grade version, while the TK suffix typically denotes specific packaging or reel configurations for manufacturing.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify cross-reference data through official Renesas channels before considering alternatives.
