Overview
The EL7516IY is a high-frequency, high-efficiency step-up voltage regulator operating in constant frequency PWM mode. It integrates an internal 1.5A power MOSFET with low on-resistance of 200mΩ. The device functions as a positive adjustable output DC-DC converter, designed for efficient power conversion in space-constrained applications.
Feature Summary
- Integrates a high-current internal power switch to minimize external component count
- Operates at high switching frequencies to reduce passive component size
- Utilizes constant frequency PWM control for stable regulation
Applications
- Portable battery-powered equipment requiring step-up voltage conversion
- Systems needing efficient power management from single-cell lithium batteries
- Space-limited circuit designs requiring integrated switching solutions
Procurement Notes
Verify the specific suffix (e.g., IY, IYZ) against the required package type and lead-free status. Confirm RoHS compliance requirements as older variants may differ. Ensure the ordering code matches the exact tape-and-reel or tube quantity needed for production integration.
Selection Notes
Select this component when a compact, high-efficiency boost regulator with integrated switching capability is required. Consider the input voltage range and desired output current relative to the internal MOSFET ratings. Evaluate thermal performance based on the selected package and ambient conditions.
Part Context
This part belongs to the Renesas 7516 group of switching regulators. The group is primarily supported for existing customers who have already adopted these products. New design-ins may require verification of current manufacturing availability and support status from the manufacturer.
Replacement Considerations
Direct substitutes include other EL7516 variants with different packaging suffixes such as EL7516IYZ. Verify pin compatibility and electrical specifications before substitution. Cross-reference with similar boost regulators if package changes are acceptable.
