Overview
The EL7566DREZ is a synchronous step-down switching voltage regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 3 V to 6 V and provides a single adjustable output from 800 mV to 6 V at up to 6 A. The device supports switching frequencies between 200 kHz and 1 MHz. It features a load regulation of -1% and functions within an operating temperature range of 0°C to +85°C. The component is housed in a 28-HTSSOP package with exposed pad for surface mount installation.
Feature Summary
- Synchronous buck topology for high efficiency
- Adjustable output voltage capability
- Integrated thermal management via exposed pad
Applications
- Point-of-load power supplies
- Embedded system voltage regulation
- Industrial control power distribution
Procurement Notes
Verify the current lifecycle status as the component may be discontinued or subject to product change notifications. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure the specific suffix matches the required packaging format. Cross-reference datasheet revisions to validate electrical parameters against design specifications before final procurement decisions.
Selection Notes
Select this regulator when a compact, high-current solution is needed for low-voltage applications. The wide input range accommodates various supply sources. Consider the thermal performance of the HTSSOP package for heat dissipation needs. Verify that the required output voltage falls within the specified 800 mV to 6 V range. Evaluate board space constraints against the 28-pin footprint dimensions.
Part Context
This part belongs to the EL7566 series of monolithic DC-DC converters. It shares functional similarities with other members like the EL7564 but offers higher current capacity. The series is designed for general-purpose power management in portable and industrial electronics. Renesas continues to support legacy Intersil products under its portfolio.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family. Verify if newer generations offer improved efficiency or extended temperature ranges. Ensure substitute components match the 6 A output requirement and 28-pin package style.
