Overview
The EL7536IY is a monolithic synchronous step-down switching voltage regulator manufactured by Renesas Electronics, formerly Intersil. It integrates high-side and low-side N-channel power FETs to deliver a continuous output current of 1 A. The device operates from an input voltage range of 2.5 V to 5.5 V and provides an adjustable output voltage between 800 mV and the input voltage. It features a fixed internal switching frequency of 1.75 MHz. The component is housed in a 10-lead MSOP package and is rated for operation over an extended temperature range of -40°C to +85°C.
Feature Summary
- Integrates synchronous N-channel power FETs for efficient step-down conversion
- Features a fixed 1.75 MHz switching frequency to minimize external component size
- Includes built-in thermal shutdown protection for enhanced reliability
Applications
- Portable battery-powered equipment
- Point-of-load regulation modules
- General-purpose DC/DC conversion circuits
Procurement Notes
Verify the specific suffix (e.g., IYZ-T7) against the required tape-and-reel quantity, as packaging variations exist within the family. Confirm RoHS compliance status via the official datasheet, as environmental declarations may vary by production lot or region. Ensure the procurement channel sources from authorized distributors to guarantee authenticity and traceability.
Selection Notes
Select this component when a compact solution with integrated power switches is required for 3.3 V or 5 V systems. The fixed 1.75 MHz frequency allows for small inductors and capacitors. Verify that the load current does not exceed the 1 A limit and that the input voltage remains within the specified 2.5 V to 5.5 V range for proper operation.
Part Context
This part belongs to the EL7536 series of single-output synchronous buck regulators. It shares functional similarities with other members like the EL7536IYZ but differs in packaging and shipping configuration. The series is designed for applications requiring high efficiency and minimal footprint in portable electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with the manufacturer's latest replacement notices or consult technical support for verified alternatives.
