Overview
The EL7531IY-T7 is a synchronous step-down DC-DC switching regulator manufactured by Renesas Electronics Corporation. It features an integrated FET design with internal compensation, supporting an input voltage range of 2.5V to 5.5V and delivering up to 1A output current. The device offers adjustable output voltage capability, operating at a fixed switching frequency of 1.4MHz. It is housed in a 10-TFSOP or 10-MSOP package (0.118" width) and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Synchronous rectification architecture for improved efficiency
- Integrated power FETs and internal compensation network
- Adjustable output voltage configuration
- Fixed high-frequency switching operation
Applications
- Portable battery-powered equipment
- Embedded systems requiring efficient step-down regulation
- Industrial control modules
- Communication infrastructure power supplies
Procurement Notes
Verify component authenticity through authorized channels due to obsolete status. Confirm package variant matches design requirements. Check RoHS compliance documentation as sources indicate potential non-compliance. Validate thermal performance against application constraints. Ensure supply chain stability given discontinuation.
Selection Notes
Evaluate input voltage compatibility with system rails. Assess thermal management needs for the 10-MSOP package. Consider availability of alternative components due to obsolescence. Verify output current requirements do not exceed 1A limit. Review PCB layout guidelines for high-frequency switching noise mitigation.
Part Context
Part of the EL7530/EL7531 family of synchronous buck regulators. Shares topology with EL7530 but offers higher current capacity. Designed for compact power solutions in space-constrained applications. Manufactured under Renesas Electronics Corporation brand following Intersil acquisition.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in verified documentation. Consider evaluating equivalent synchronous buck regulators from other manufacturers if redesign is necessary.
