EL7531IY-T13

Overview

The EL7531IY-T13 is a synchronous step-down PWM regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range from 2.5V to 5.5V, accommodating supplies of 3.3V, 5V, or Li-Ion battery sources. The device provides an output current capability of 1A and features an adjustable output voltage range from 0.8V to V_IN via an external resistive divider. It utilizes a fixed switching frequency of 1.6MHz and includes internal compensation. The component is housed in a 10-lead MSOP package.

Feature Summary

Synchronous integrated FET design for high efficiency
Internal compensation simplifies external component requirements
Adjustable output voltage via resistive divider
Integrated protection against short circuits and over-temperature

Applications

Portable electronics powered by single-cell lithium-ion batteries
Point-of-load regulation for digital signal processors
General-purpose DC-DC conversion for embedded systems

Procurement Notes

Verify the specific suffix T13 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as historical Intersil data may vary. Ensure the supplier source is authorized to guarantee authenticity for this discontinued or limited-stock part number.

Selection Notes

Select this component for applications requiring a compact solution with minimal external components due to internal compensation. It is suitable where input voltages are between 2.5V and 5.5V and output currents up to 1A are needed. Consider the MSOP-10 package constraints for thermal management.

Part Context

This part belongs to the EL753x series of synchronous buck regulators from Renesas/Intersil. It shares architectural similarities with the EL7532 and EL7535 but differs in output current ratings and specific package options within the same family of power management ICs.
