ISL9305IRTWCNYZ-T

Overview

The ISL9305IRTWCNYZ-T is a mini-PMIC featuring two 3MHz synchronous buck converters and two low-input LDOs. Output 1 provides 1.2V at 800mA, while Output 2 delivers 1.8V. The device supports an input voltage range of 1.5V to 5.5V and operates within a temperature range of -40°C to 85°C. It utilizes an I2C-compatible interface for configuration and monitoring. The component is housed in a 16-TQFN (4x4) package with an exposed pad for thermal dissipation.

Feature Summary

• Integrates dual step-down converters and dual linear regulators in a single compact package
• Supports I2C compatible interface for digital control and status monitoring
• Designed for powering low-voltage microprocessors and multiple voltage rails

Applications

• Powering low-voltage microprocessors
• Systems requiring multiple distinct voltage rails
• Portable electronic devices with space constraints

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Production has ceased, and no new units will be stocked once existing inventory is depleted. Procurement is restricted to remaining stock from authorized distributors or secondary markets. Verify part authenticity and condition carefully, as availability is limited and supply chain continuity cannot be guaranteed for future production runs.

Selection Notes

Select this component only if legacy compatibility is required for existing designs utilizing the ISL9305 family. Due to its obsolete status, alternative solutions should be evaluated for new projects. Ensure that the specific output voltages and current ratings meet the system requirements without modification. Consider the physical footprint and thermal characteristics of the 16-TQFN package during PCB layout planning.

Part Context

The ISL9305 series represents Renesas Electronics' integrated mini-Power Management IC solution. This specific variant combines switching and linear regulation technologies to provide efficient power delivery. The model suffix indicates specific packaging and tape-and-reel configuration details consistent with the broader product line's manufacturing standards.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the product is obsolete, engineers must design around existing stock or select entirely different PMIC families that offer similar functionality and pin compatibility.
