ISL9305IRTWBNLZ-T

Overview

The ISL9305IRTWBNLZ-T is an integrated mini Power Management IC (mini-PMIC) manufactured by Renesas Electronics Corporation. It features four outputs: two buck regulators and two low-dropout linear regulators (LDOs). The device operates with a supply voltage range of 1.5V to 5.5V and supports a switching frequency of 3MHz. Output specifications include 1.5V at 800mA, 2.5V at 800mA, and 3.3V at 350mA. It is housed in a 16-TQFN (4x4mm) package with an exposed pad, designed for surface mount installation. The component functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates two step-down buck converters and two LDO regulators into a single compact package
• Optimized for powering low-voltage microprocessors and multiple system voltage rails
• Supports high-frequency operation at 3MHz to minimize external passive component size

Applications

• Low-voltage microprocessor power systems
• Multi-rail embedded electronic devices
• Portable consumer electronics requiring compact power solutions

Procurement Notes

Verify the obsolete status of this part number before procurement planning. The manufacturer has issued a Product Change Notification indicating end-of-life production. Ensure alternative sourcing strategies or design-in replacements are evaluated immediately to prevent supply chain disruption for existing products.

Selection Notes

Select this component only if the specific output voltages and current ratings align with the target design requirements. Consider the 16-TQFN footprint constraints during PCB layout. Evaluate thermal performance under maximum load conditions due to the compact package size and integrated topology.

Part Context

This part belongs to the ISL9305 family of mini-PMICs from Renesas. These devices are engineered to consolidate multiple power rails into a single solution, reducing board space and simplifying power distribution networks for portable and embedded applications compared to discrete regulator implementations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must identify functional equivalents based on pin compatibility and electrical specifications through independent cross-reference tools.
