ISL6534CVZ

Overview

The ISL6534CVZ is a versatile triple regulator IC from Intersil, housed in a TSSOP-24 package. It integrates two independent synchronous-rectified buck controllers with integrated 12V gate drivers for OUT1 and OUT2, alongside one linear regulator (LDO). The switching controllers operate within a frequency range of 300kHz to 1MHz. This component serves as a power management solution designed for applications requiring multiple regulated voltage rails.

Feature Summary

• Integrates two independent synchronous-rectified buck controllers with built-in 12V gate drivers
• Includes an additional linear regulator (LDO) channel for auxiliary power needs
• Supports adjustable switching frequencies between 300kHz and 1MHz

Applications

• Industrial equipment power systems
• Medical equipment power supplies
• Multi-rail server or communication infrastructure

Procurement Notes

Verify the manufacturer designation, as Intersil assets are managed by Renesas. Confirm the specific suffix 'CVZ' corresponds to the commercial temperature range and TSSOP-24 package. Ensure compatibility with existing PCB footprints and thermal requirements before procurement.

Selection Notes

Select this component when a single IC solution is required for dual synchronous buck conversion and one LDO output. Consider the 300kHz-1MHz frequency range for inductor size trade-offs. Verify that the 12V integrated gate drivers meet the requirements for the external MOSFETs used in the design.

Part Context

The ISL6534 series belongs to the PMIC - Voltage Regulators - Linear + Switching category. It is part of a family of triple regulators designed to simplify power architecture by combining switching and linear regulation technologies in a compact form factor.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISL6534 family, such as variants with different temperature ratings or packaging options, ensuring functional equivalence of the dual buck and single LDO configuration.
