Overview
The EL7518IWTZ-T7A is an LED driver IC featuring a DC-DC step-up (boost) regulator. It operates within an input voltage range of 2.6V to 13.2V and provides a single output up to 18V. The device is housed in an 8-pin TSOT package and is supplied in tape and reel format.
Feature Summary
- Integrated DC-DC boost converter for LED regulation
- Supports dimming control capabilities
- Compact TSOT-23-8 packaging
Applications
- LED lighting systems requiring step-up voltage regulation
- Portable devices with battery-powered LED indicators
- General-purpose LED driver circuits
Procurement Notes
Verify the manufacturer designation, as Intersil operations are now part of Renesas. Confirm the specific suffix 'T7A' corresponds to the required tape and reel packaging configuration. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Cross-reference the datasheet FN7858 or equivalent for detailed electrical characteristics.
Selection Notes
Select this component when a compact solution for driving LEDs from a lower voltage source is required. The integrated boost regulator simplifies circuit design by eliminating external inductors or complex topologies. Consider the 18V maximum output and 13.2V input limits to ensure compatibility with the target LED string voltage and supply rails.
Part Context
This part belongs to the Intersil LED driver family, specifically designed for efficient power management in lighting applications. The TSOT-23-8 package allows for space-constrained designs. As an Intersil product, it reflects the company's expertise in analog and mixed-signal semiconductor solutions prior to its acquisition by Renesas.
Replacement Considerations
Direct substitutes may include other Intersil/Renesas LED drivers with similar boost architectures and TSOT-23-8 packages. Verify pinout compatibility and electrical specifications such as switching frequency and current limits before substitution.
