EL7531IYZ-T13

Overview

The EL7531IYZ-T13 is a monolithic 1A step-down switching regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range from 2.5V to 5.5V, accommodating 3.3V, 5V, or Li-Ion battery sources. The device features a fixed internal switching frequency of 1.6MHz and delivers an output current of 1.2A. The adjustable output voltage ranges from 800mV to 5.5V. It utilizes a 10-pin MSOP package and supports surface mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates synchronous FETs for high-efficiency power conversion
Includes internal compensation to simplify external component requirements
Provides comprehensive protection against short circuits and over-temperature conditions

Applications

Portable electronics powered by single-cell lithium-ion batteries
Embedded systems requiring regulated 3.3V or 5V logic supplies
Industrial control modules operating from standard bus voltages

Procurement Notes

Verify the specific suffix T13 indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation as availability varies. Check for End-of-Life (EOL) notices or Last Time Buy dates directly from Renesas. Ensure the MSOP-10 package dimensions match the target PCB footprint constraints before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution is required for low-voltage step-down applications. The 1.6MHz frequency allows for smaller passive components compared to lower-frequency regulators. Verify that the load current does not exceed the 1.2A rating under all thermal conditions. Consider the 10-pin MSOP package size relative to available board space in dense designs.

Part Context

This part belongs to the EL7531 series of monolithic step-down regulators. It shares architectural similarities with the EL7530 and EL7532 models but offers distinct current ratings and switching frequencies. The series targets portable and industrial applications requiring efficient power management from single-cell battery sources or standard voltage rails.
