EL7564CMZ

Overview

The EL7564CMZ is a monolithic step-down switching voltage regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 4.5 V to 5.5 V and provides a single adjustable positive output ranging from 1 V to 3.8 V. The device supports up to 4 A of output current and features a synchronous rectifier topology. It functions within a switching frequency range of 200 kHz to 1 MHz and is rated for operation between -40°C and +85°C. The component is housed in a 20-SOIC package.

Feature Summary

• Synchronous buck converter topology for high efficiency
• Adjustable output voltage capability
• Integrated high-current power stage

Applications

• Portable electronic devices requiring stable power regulation
• Embedded systems utilizing single-cell battery inputs
• General-purpose DC-DC conversion circuits

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require verification through authorized distributors or secondary markets. Buyers should confirm current stock status and authenticity carefully before procurement due to the discontinued production status.

Selection Notes

Select this part only if the specific 4.5 V to 5.5 V input window and 4 A current capacity align with system requirements. The 20-SOIC package necessitates adequate PCB space. Consider that the adjustable output range is limited to 1 V minimum, which may not suit low-voltage logic cores requiring lower rails without additional regulation stages.

Part Context

The EL7564CMZ belongs to the EL7564 series of monolithic DC-DC step-down regulators. It is designed for applications needing efficient power conversion from a nominal 5 V source. The series typically targets portable electronics and embedded systems where size and efficiency are critical constraints.
