Overview
The EL7566DRE is a synchronous step-down switching regulator manufactured by Renesas Electronics, formerly Intersil. It operates as a Buck converter with a fixed output current capability of 6 A and an adjustable output voltage range from 800 mV to 6 V. The device supports a switching frequency between 200 kHz and 1 MHz. It is housed in an HTSSOP-EP-28 package designed for surface mount installation. The component functions within an operating temperature range of 0°C to +85°C and exhibits a load regulation of -1%.
Feature Summary
- Synchronous buck topology for high efficiency
- Integrated power switches for compact design
- Adjustable switching frequency for optimization
Applications
- Point-of-load voltage regulation
- Industrial control systems
- Telecommunications infrastructure
Procurement Notes
Verify the specific suffix (e.g., DRE vs DREZ) against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Check for end-of-life notifications or obsolescence notices directly from Renesas to avoid supply chain disruptions during production planning.
Selection Notes
Select this component when a 6 A continuous output current is required for space-constrained applications. Ensure the input voltage exceeds the maximum desired output voltage plus the dropout requirement. Verify that the external inductor and capacitor values align with the specified switching frequency range to maintain stability and thermal performance within the rated operating temperature limits.
Part Context
This part belongs to the EL7566 series of DC-DC converters. It is a legacy product originally developed by Intersil before the company's acquisition by Renesas Electronics. The device represents a generation of synchronous regulators designed to replace linear regulators in medium-power applications requiring higher efficiency and lower heat dissipation.
Replacement Considerations
Consult the official Renesas cross-reference guide for verified substitutes. Generic equivalents may not match the exact pinout or thermal characteristics of the HTSSOP-EP-28 package.
