Overview
The EL7515IYZ is a high-frequency, high-efficiency boost DC/DC switching regulator IC manufactured by Renesas Electronics. It operates in fixed-frequency PWM mode and integrates a 1.4A MOSFET to deliver up to 600mA output current with efficiencies reaching 92%. The device accepts input voltages from 1.8V to 13.2V and provides an adjustable positive output voltage ranging from 4.5V to 17V. It functions within an operating temperature range of -40°C to +85°C and is housed in a 10-MSOP package.
Feature Summary
- Integrates a 1.4A power MOSFET for efficient step-up conversion
- Operates in fixed-frequency PWM mode for stable regulation
- Supports wide input voltage range suitable for battery-powered applications
Applications
- Portable electronic devices requiring voltage boosting
- Battery-powered systems needing regulated higher voltage rails
- General-purpose power management in compact form factors
Procurement Notes
Verify the specific suffix (e.g., IYZ vs IYZ-T7) against official Renesas documentation to confirm tape-and-reel packaging or lead-free status. Confirm availability as distribution status may vary. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when a compact boost converter with integrated high-current MOSFET is required. The fixed PWM frequency simplifies filter design compared to variable frequency alternatives. Consider the 10-MSOP package constraints for PCB layout and thermal dissipation requirements relative to the expected load current.
Part Context
This part belongs to the EL7515 series of switching regulators designed for space-constrained applications. It represents a solution for stepping up low input voltages to higher levels efficiently. The integration of the power switch reduces external component count compared to discrete solutions.
Replacement Considerations
Consult official Renesas substitution guides for verified equivalents. Generic replacements must match the 10-MSOP footprint, 1.4A current capability, and 1.8V–13.2V input range. Verify pin compatibility and control interface before implementation.
