Overview
The ISL97682IRTZ-TR5509 is a DC-DC regulator LED driver IC manufactured by Renesas Electronics Corporation. It features a boost topology with two internal switches and outputs, delivering up to 100mA per channel. The device operates on a supply voltage range of 4V to 45V and supports PWM dimming for backlight applications. It is housed in a 16-TQFN (3x3) package with an exposed pad.
Feature Summary
- Integrates dual-channel boost converters with internal switching elements
- Supports high-voltage input ranges suitable for series LED strings
- Enables precise brightness control via pulse-width modulation dimming
Applications
- LED backlighting systems
- High-voltage LED string drivers
- Portable electronic display illumination
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix TR5509 matches your reel requirements. Check RoHS compliance status and moisture sensitivity level before assembly. Ensure ESD protection protocols are followed during handling due to the TQFN package type.
Selection Notes
Select this part when dual independent LED channels are required within a compact footprint. The wide input voltage range accommodates various battery configurations. Verify that the 100mA output current meets the target LED forward current specifications. Consider thermal performance requirements associated with the exposed pad design.
Part Context
This component belongs to the ISL97682 family of LED lighting drivers. It shares architectural similarities with other models in the series but differs in output count and packaging variations. The device represents Renesas's solution for efficient power management in portable display applications requiring regulated constant current sources.
Replacement Considerations
Direct substitutes include ISL97682IRTZ and ISL97682IRTZ-TK. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement variant maintains the same TQFN package dimensions and thermal characteristics.
