EL7554IREZ-T7

Overview

The EL7554IREZ-T7 is a synchronous step-down switching regulator IC manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 3V to 6V and provides a single adjustable output from 0.8V to 6V, delivering up to 4A of continuous current. The device supports a switching frequency between 200kHz and 1MHz. It is housed in a 28-HTSSOP package with an exposed pad for thermal management. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

Synchronous rectification architecture for high efficiency
Adjustable output voltage via external resistor divider
Wide input voltage compatibility for flexible power designs

Applications

Portable electronic devices requiring efficient power conversion
Embedded systems with low-voltage logic requirements
Industrial control modules needing stable regulated power

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations exist within the EL7554 series. Confirm availability status directly with the manufacturer or authorized distributors, as discontinuation notices may apply. Ensure compliance with RoHS3 specifications and moisture sensitivity level (MSL) handling procedures during storage and assembly processes.

Selection Notes

Select this component when a compact, high-current buck converter is required for inputs up to 6V. The 28-pin HTSSOP package suits applications with moderate space constraints. Evaluate thermal performance based on the exposed pad design and expected load currents. Consider the adjustable output range and switching frequency flexibility for optimizing external component selection.

Part Context

This part belongs to the EL7554 family of synchronous buck regulators from Renesas. The 'T7' suffix typically indicates reel packaging, distinct from tube-packaged variants like the EL7554IREZ. The family is designed for general-purpose DC-DC conversion, emphasizing efficiency and integration in a small footprint suitable for modern portable electronics.
