EL7530IYZ-T7

Overview

The EL7530IYZ-T7 is a monolithic synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.5 V to 5.5 V and provides an adjustable output voltage from 800 mV to 5.5 V. The device delivers a maximum output current of 600 mA at a fixed switching frequency of 1.6 MHz. It is housed in a compact 10-lead MSOP package and supports surface-mount installation. The component functions as a single-output DC-DC converter designed for efficient power management in space-constrained applications.

Feature Summary

• Integrates synchronous rectification to enhance conversion efficiency within a compact footprint.
• Features a fixed high-frequency switching architecture to minimize external passive component requirements.
• Provides adjustable output voltage capability to accommodate various load requirements.

Applications

• Portable battery-powered electronic devices
• Embedded systems requiring efficient DC-DC conversion
• General-purpose power management circuits

Procurement Notes

This component is officially designated as obsolete or end-of-life by the manufacturer. Verification of availability should focus on surplus distributors rather than direct supply channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to procurement. Ensure that any sourced units match the original datasheet specifications, as obsolescence may affect long-term supply continuity and quality assurance protocols.

Selection Notes

Select this part only if the application strictly requires a 600 mA synchronous buck regulator with a 1.6 MHz switching frequency. Verify that the required output voltage falls within the 800 mV to 5.5 V adjustable range. Consider the 10-MSOP package constraints for PCB layout. Due to its obsolete status, evaluate alternative components from the same family or newer generations that offer similar electrical characteristics and availability.

Part Context

The EL7530IYZ-T7 belongs to the EL7530 series of monolithic switching regulators. It is part of Renesas Electronics' portfolio of power management integrated circuits (PMIC). The 'T7' suffix indicates reel packaging. This specific variant is a discontinued product within the broader EL7530 family, which includes other packaging options like tube and cut tape variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Renesas replacement guides or contact authorized distributors for qualified alternatives compatible with the EL7530 series specifications.
