Overview
The EL7513IY-T7 is a constant current boost regulator IC designed for driving white LEDs. It supports driving up to four LEDs in series or up to twelve LEDs in parallel/series configurations. The device operates with a PWM dimming interface and provides a regulated output current of 500mA. It is housed in an 8-MSOP package.
Feature Summary
- Constant current boost regulation architecture optimized for white LED applications
- Supports flexible LED topologies including series strings and parallel/series combinations
- Integrated PWM dimming control interface for brightness adjustment
Applications
- White LED backlighting systems
- Portable electronic device illumination
- General lighting modules requiring regulated LED drive
Procurement Notes
Verify the specific manufacturer source, as the component history involves Intersil Corporation prior to acquisition by Renesas Electronics. Confirm that the 8-MSOP package designation matches the physical requirements of the target PCB footprint. Ensure the T7 suffix corresponds to the correct tape and reel quantity specified in the official documentation.
Selection Notes
Select this component when a dedicated boost regulator for white LEDs is required rather than a general-purpose power supply. The fixed 500mA output current rating dictates suitability for medium-brightness LED arrays. Consider the MSOP package size constraints relative to available board space and thermal dissipation capabilities of the application environment.
Part Context
This part belongs to the EL7513 family of LED drivers. It functions specifically as a step-up converter tailored for high-efficiency white LED operation. The technology lineage traces from Intersil to Renesas Electronics Corporation, maintaining functional compatibility within the established product line specifications.
Replacement Considerations
Consult official substitution lists for equivalent parts from the same manufacturer family. Verify pinout compatibility and electrical parameter alignment before replacing the component in existing designs.
