ISL8510IRZ

Overview

The Intersil ISL8510IRZ is a dual-output power management integrated circuit designed for point-of-load applications. It integrates a high-frequency 500kHz switching buck regulator and an integrated linear (LDO) regulator within a single package. This configuration provides a compact, high-performance solution for generating multiple voltage rails efficiently. The device operates within a temperature range of -40°C to +85°C and is housed in a 24-pin VQFN exposed pad package.

Feature Summary

• Integrates a 500kHz PWM buck controller with an LDO for combined switching and linear regulation
• Provides a single-chip dual-output solution for space-constrained point-of-load designs
• Supports industrial operating temperatures from -40°C to +85°C

Applications

• Point-of-load voltage regulation in industrial equipment
• Power management for communication infrastructure
• Dual-rail supply generation in embedded systems

Procurement Notes

Verify the manufacturer source carefully, as Intersil was acquired by Renesas Electronics. Ensure the component matches the original Intersil specifications or confirm if it is a Renesas-branded equivalent. Check for RoHS compliance status and verify the specific suffix 'IRZ' indicates the correct temperature grade and packaging variant required for your design.

Selection Notes

Select this component when a design requires both efficient switching conversion and low-noise linear regulation from a single footprint. It is suitable for applications needing a primary stepped-down voltage via the buck converter and a secondary clean rail via the LDO. Consider the 24-pin VQFN package constraints and thermal dissipation requirements for the exposed pad during layout.

Part Context

The ISL8510 series belongs to the Intersil portfolio of advanced power management ICs, now maintained under Renesas Electronics following the corporate acquisition. These devices are engineered for high-density power solutions in analog-intensive environments. The IRZ suffix typically denotes the lead-free, RoHS-compliant version in a VQFN package.

Replacement Considerations

Consult Renesas Electronics product legacy documents for officially confirmed substitute part numbers. Verify pin compatibility and electrical parameters before replacing the original Intersil unit with any alternative.
