EL7513IY-T13

Overview

The EL7513IY-T13 is a monolithic constant current boost regulator designed for driving white LEDs. Manufactured by Renesas Electronics Corporation, it operates with an input voltage range of 2.5V to 6V and delivers a regulated output current of up to 500mA. The device supports PWM dimming control and functions at a switching frequency of 1.6MHz. It is housed in an 8-MSOP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated constant current boost topology optimized for LED string driving
• Supports high-resolution pulse-width modulation (PWM) dimming control
• Monolithic design reduces external component count

Applications

• White LED backlighting systems
• Portable electronic device illumination
• General-purpose LED driver circuits

Procurement Notes

Verify the specific suffix T13 indicates tape and reel packaging configuration. Confirm RoHS compliance status through official Renesas documentation as availability varies. Check for end-of-life notices or obsolescence warnings prior to finalizing procurement plans.

Selection Notes

Select this component when a compact, single-inductor boost solution is required for white LED arrays. Ensure the application input voltage remains within the 2.5V to 6V operational window. Verify that the 500mA current capability aligns with the target LED string requirements.

Part Context

This part belongs to the EL75xx series of power management ICs from Renesas. It serves as a specialized driver within the company's portfolio for portable consumer electronics, focusing on efficient light source regulation in space-constrained designs.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully before integrating any substitute components into existing designs.
