Overview
The EL7513IYZ is an obsolete LED driver IC manufactured by Renesas Electronics Corporation. It functions as a DC-DC regulator with a step-up (boost) topology, designed specifically for driving LEDs. The device features a single output capable of delivering up to 500mA and supports PWM dimming control. It is housed in an 8-TSSOP or 8-MSOP package.
Feature Summary
- Integrates a boost converter topology for efficient LED current regulation
- Supports pulse-width modulation (PWM) dimming for brightness control
- Provides regulated constant current output for LED segments
Applications
- LED segment display drivers
- Backlighting systems requiring boost conversion
- Portable electronic devices with limited power supply voltage
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Ensure the part number matches exactly, including suffixes if applicable, as packaging variations exist. Validate datasheet revisions and confirm lead times carefully due to end-of-life status.
Selection Notes
Designers seeking this specific obsolete part must evaluate alternative components from the same family or newer generations that offer similar boost topology and current capabilities. Verify pin compatibility and electrical specifications against new candidates to ensure seamless integration without redesigning the PCB layout or control circuitry.
Part Context
The EL7513IYZ belongs to Renesas' legacy portfolio of display drivers and power management ICs. It was engineered for applications requiring compact solutions for driving multiple LED segments from low-voltage sources. Its classification as a DC-DC regulator highlights its role in converting input voltage to the higher levels needed for LED operation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult Renesas technical support or distributor catalogs for cross-reference recommendations based on specific application requirements.
