Overview
The EL7566DREZ-T13 is a synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 3 V to 6 V and delivers a maximum output current of 6 A. The device provides an adjustable output voltage between 800 mV and 6 V with a single output configuration. It supports a switching frequency range from 200 kHz to 1 MHz. The component is housed in a 28-HTSSOP package with exposed pad for surface mount installation. It functions within an operating temperature range of 0°C to +85°C.
Feature Summary
- Synchronous rectification architecture for improved efficiency
- Adjustable output voltage capability via external resistor network
- Wide switching frequency selection for optimization of transient response and component size
Applications
- Point-of-load regulation for digital signal processors
- Power supply stages for field-programmable gate arrays
- Voltage conversion for embedded memory subsystems
Procurement Notes
Verify the specific suffix T13 indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation as environmental declarations may vary by production batch. Check for End-of-Life notices or Product Change Notifications regarding availability and long-term supply continuity before finalizing design-in decisions.
Selection Notes
Select this component when a high-current buck converter is required for low-voltage input applications. Ensure the thermal design accommodates the power dissipation inherent in the 28-HTSSOP package at full load. Verify that the required output voltage falls within the 800 mV to 6 V adjustment range. Consider the switching frequency requirements against electromagnetic interference constraints and inductor size limitations.
Part Context
This part belongs to the EL7566 series of monolithic DC-DC step-down regulators. The series is designed for applications requiring efficient power conversion from standard 3.3 V or 5 V rails to lower logic voltages. The DREZ suffix denotes the specific HTSSOP-EP-28 package variant, distinguishing it from other pinout or thermal options within the same functional family.
Replacement Considerations
Consult official manufacturer substitution guides for verified alternatives. Cross-reference electrical parameters such as output current capacity, input voltage limits, and package dimensions to ensure compatibility.
