ISL6442IAZ-TKS2715

Overview

The ISL6442IAZ-TKS2715 is a Power Management Integrated Circuit (PMIC) manufactured by Renesas Electronics Corporation. It integrates three output regulators: two synchronous buck converters and one low-dropout linear regulator (LDO). The device operates with a supply voltage range of 4.5V to 5.5V and supports adjustable switching frequencies between 300kHz and 2.55MHz. It is housed in a 24-QSOP surface-mount package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates dual synchronous buck and single LDO regulators for multi-rail power distribution
• Supports wide-range programmable switching frequency from 300kHz to 2.55MHz
• Designed for compact surface-mount applications using the 24-QSOP package

Applications

• Portable electronic devices requiring efficient multi-voltage regulation
• Industrial control systems needing synchronized power rails
• Embedded computing platforms utilizing PMIC solutions

Procurement Notes

Verify component authenticity through authorized distributors or official Renesas channels. Confirm RoHS3 compliance and check for specific tape-and-reel packaging requirements associated with the TKS2715 suffix. Ensure compatibility with existing PCB footprints and thermal management designs before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution for dual buck and single LDO outputs is required. Consider the 24-QSOP package constraints and the specified input voltage window. Evaluate the need for the specific switching frequency range against system noise and efficiency targets compared to alternative fixed-frequency regulators.

Part Context

This part belongs to the ISL6442 family of triple-output PMICs. It serves as a replacement for obsolete models like the ISL6445 and ISL6446, offering similar functionality in a consolidated package. The TKS2715 suffix indicates a specific tape-and-reel packaging configuration distinct from standard tube packaging.

Replacement Considerations

The ISL6442IAZ is listed as a parametric equivalent substitute for the ISL6445IAZ and ISL6446IAZ.
