EL7564CREZ

Overview

The EL7564CREZ is a monolithic 4Amp DC:DC step-down regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 4.5V to 5.5V and provides an adjustable output voltage from 1V to 3.8V. The device supports a switching frequency between 200kHz and 1MHz, delivering up to 4A of output current with a single output configuration. It utilizes synchronous rectification for improved efficiency and is housed in a TSSOP-28 package. The component functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

Monolithic buck converter topology designed for high-efficiency power conversion
Integrated synchronous rectification to minimize conduction losses
Adjustable output voltage capability for flexible system design
High current delivery suitable for demanding load applications

Applications

Point-of-load regulation for digital signal processors
Power supply stages for embedded computing systems
Voltage regulation in industrial control equipment
Power management for communication infrastructure modules

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm package type and temperature rating. Ensure compatibility with existing PCB footprints for the TSSOP-28 configuration. Confirm that the selected variant meets all required thermal and electrical specifications for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a compact, high-current step-down solution is required for 5V input systems. The adjustable output allows precise voltage setting for various logic levels. Consider the thermal performance requirements associated with 4A continuous current operation. Verify that the switching frequency range aligns with external component selection for optimal ripple and transient response characteristics.

Part Context

This part belongs to the EL7564 series of switching voltage regulators produced by Renesas Electronics. The series includes variants such as the EL7564CMZ, which shares similar functional characteristics but differs in packaging. These devices are classified under PMIC - Power Management ICs, specifically as switching voltage regulators designed for efficient DC-DC conversion in portable and industrial electronics.
