Overview
The ISL6442IAZ-TK is a triple-output power management IC manufactured by Renesas Electronics Corporation. It integrates two synchronous step-down (buck) converters and one linear regulator (LDO). The switching frequency range spans from 300kHz to 2.55MHz, with an operating temperature range of -40°C to 85°C. The device is housed in a 24-QSOP package and supports an input voltage range of 4.5V to 5.5V.
Feature Summary
- Integrates dual synchronous buck converters for efficient high-current regulation
- Includes a single low-dropout linear regulator for noise-sensitive loads
- Supports wide adjustable switching frequencies up to 2.55MHz
Applications
- Portable computing systems requiring multiple voltage rails
- Industrial control boards needing mixed linear and switching regulation
- Communication equipment utilizing synchronized buck topologies
Procurement Notes
Verify the suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm RoHS3 compliance status and check for any Product Change Notices regarding lead finish or marking updates before finalizing procurement orders.
Selection Notes
Select this component when a compact solution combining synchronous buck efficiency with LDO precision is required. Ensure the design accommodates the 24-QSOP thermal requirements and that the input voltage remains within the specified 4.5V to 5.5V window for stable operation across the full temperature range.
Part Context
This part belongs to the ISL6442 family of PMICs designed for applications requiring three distinct output voltages from a single chip. It serves as a consolidated power solution, reducing board space compared to discrete regulator implementations while maintaining high efficiency through synchronous rectification.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative components such as the ISL81802FRTZ-T only if explicitly validated by manufacturer cross-reference data.
