EL7513IY

Overview

The EL7513IY is a constant current boost regulator IC designed for driving white LEDs. It supports configurations of up to four LEDs in series or twelve in parallel/series. The device operates with an output voltage of 18V and delivers a channel current of 500mA at a switching frequency of 1MHz. It features PWM dimming capabilities and is housed in an 8-MSOP surface-mount package.

Feature Summary

• Constant current boost regulation architecture
• Supports complex LED arrays (series, parallel, or mixed)
• Integrated PWM dimming control interface

Applications

• LED backlighting systems
• White LED driver circuits

Procurement Notes

Verify component status as the EL7513IY is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing design specifications before procurement. Check for valid replacement options if new production is required.

Selection Notes

Select this component for applications requiring a single-output boost regulator for white LEDs. Consider the 500mA output current and 18V maximum output voltage limits. Evaluate the 8-MSOP package size against board space constraints. Verify thermal management requirements for the operating temperature range.
