Overview
The Intersil EL7513AIWTZ-T7 is a constant current boost regulator 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 an input voltage range of 2.7V to 5.5V and provides an output current capability of 0.5A. It features a switching frequency of 1.2MHz and functions within a temperature range of -40°C to +85°C. The component is housed in a TSSOP-16 package.
Feature Summary
- Integrated constant current boost topology optimized for LED string driving
- Supports flexible LED configurations including series and parallel arrangements
- High switching frequency enables the use of compact external passive components
Applications
- White LED backlighting for portable electronic devices
- General purpose LED illumination systems
- Battery-powered lighting applications requiring efficient power conversion
Procurement Notes
Verify the specific suffix 'T7' corresponds to the required tape and reel packaging quantity as defined by the manufacturer's official documentation. Confirm that the 'A' grade designation meets the required operational temperature and performance specifications for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a compact, high-efficiency solution is needed for driving multiple white LEDs from a single-cell lithium battery source. Ensure the design accommodates the 1.2MHz switching frequency requirements for inductor selection. Verify that the load configuration does not exceed the maximum supported LED count or current limits specified in the electrical characteristics table.
Part Context
This part belongs to the Intersil EL7513 family of LED drivers. It is manufactured by Renesas Electronics, which acquired Intersil. The device is classified under Power Management ICs (PMIC) specifically within the LED Driver subcategory. It serves as a specialized power supply controller for visual display and lighting subsystems.
Replacement Considerations
Consult official Renesas discontinuation notices for confirmed substitute part numbers. Generic equivalents may not match the specific control loop characteristics or pinout compatibility required for direct replacement without schematic modification.
