EL7516IYZ-T13

Overview

The EL7516IYZ-T13 is a high-frequency, high-efficiency step-up voltage regulator manufactured by Renesas Electronics Corporation. It operates in constant frequency PWM mode with selectable switching frequencies of 600 kHz or 1.2 MHz. The device integrates an internal 1.5A power MOSFET and supports positive adjustable output voltages starting from 2.6V. It is housed in an 8-lead MSOP package (0.118 inch width) and is designed for applications requiring efficient DC-DC conversion with compact form factors.

Feature Summary

• Integrates a 1.5A internal power MOSFET for efficient step-up regulation
• Supports dual switching frequencies of 600 kHz and 1.2 MHz for optimized design flexibility
• Operates in constant frequency PWM mode to ensure stable performance

Applications

• Portable battery-powered equipment
• Cellular phones and PDAs
• Digital cameras
• Handheld instruments

Procurement Notes

Verify the specific suffix T13 indicates reel packaging when sourcing. Confirm the manufacturer designation as Renesas Electronics Corporation, noting historical Intersil branding may appear in legacy documentation. Ensure the MSOP-8 package dimensions match the 0.118-inch width specification for PCB layout compatibility. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a compact step-up solution with integrated power switching is required. The dual frequency option allows trade-offs between component size and efficiency. Ensure input voltage ranges align with the source supply and that the load current does not exceed the internal MOSFET capabilities. Verify thermal management needs based on the expected duty cycle and ambient conditions.

Part Context

This part belongs to the EL7516 series of step-up regulators. It is distinct from buck converters like the EL7535 and operational amplifiers such as the EL5204. The IYZ suffix denotes the MSOP package variant, while T13 specifies the tape and reel delivery method. It serves as a power management IC within the broader portfolio of analog and mixed-signal products.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternatives based on matching topology (boost), current rating (1.5A), and package type (MSOP-8). Cross-reference pinouts and control interfaces carefully, as functional equivalents may differ in external component requirements or frequency selection methods.
