ISL6531CRZ-T

Special Purpose Regulators Overview

The ISL6531CRZ-T is a dual synchronous buck pulse-width modulator (PWM) controller manufactured by Renesas Electronics Corporation. Designed for DDR memory power applications, it regulates VDDQ and VTT termination voltages. The device operates from a 5V supply and features internal compensation for input voltage and load variations. It is housed in a 32-lead QFN package with exposed pad, suitable for surface-mount assembly.

Special Purpose Regulators Feature Summary

• Dual output control for synchronized VDDQ and VTT regulation
• Internal compensation circuitry stabilizes performance under varying conditions
• Optimized for low-profile surface-mount integration

Special Purpose Regulators Applications

• DDR SDRAM memory power supplies
• VDDQ termination voltage regulation
• VTT termination voltage regulation

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status as historical data indicates potential non-compliance for older batches. Check for lead-free markings on the package. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering to prevent package damage during assembly.

Special Purpose Regulators Selection Notes

Select this controller for designs requiring dedicated dual-channel PWM management for DDR memory interfaces. Evaluate thermal performance due to the QFN package constraints. Verify that the internal compensation aligns with the specific decoupling network of the target memory module. Consider availability status as legacy components may have limited production runs.

Special Purpose Regulators Part Context
