EL7563CRE-TZ

Overview

The EL7563CRE-TZ is a monolithic, full-featured synchronous step-down DC/DC regulator manufactured by Elantec (now Renesas). It integrates high-side and low-side MOSFETs with a current mode controller to deliver up to 4A of continuous output current. The device operates from a 3V to 3.6V input supply range and supports adjustable output voltages between 1.0V and 2.5V. Key electrical parameters include ±0.5% load and line regulation, an adjustable switching frequency up to 1MHz, and peak efficiency reaching 95%. It utilizes patented on-chip resistorless current sensing for cycle-by-cycle protection.

Feature Summary

Integrated synchronous MOSFETs and current mode controller
Patented on-chip resistorless current sensing
Power tracking for multi-supply start-up sequencing
Junction temperature indicator for thermal monitoring

Applications

Desktop computer power systems
Portable electronic devices
Point-of-load voltage regulation

Procurement Notes

Verify the manufacturer designation, as Elantec was acquired by Intersil and subsequently Renesas. Confirm the specific suffix 'TZ' indicates RoHS compliance and lead-free status. Ensure the package type matches the required 28-pin HTSSOP footprint. Cross-reference the datasheet revision to confirm feature availability such as synchronization capabilities.

Selection Notes

Select this component when a compact solution is required for low-voltage, high-current applications. The integrated design minimizes external component count compared to discrete solutions. Consider the 3V to 3.6V input constraint and ensure the load requirements do not exceed the 4A continuous current limit. Verify that the adjustable output range covers the target system voltage needs.

Part Context

This part belongs to the EL756x series of synchronous buck regulators. It shares architectural similarities with the EL7564 but differs in pinout and specific integration features. The series is designed for applications requiring high efficiency and small form factors. The CRE-TZ variant specifically denotes the commercial temperature range and TSSOP/HTSSOP packaging options available within the product line.
