ISL9305IRTHWLNCZ-T

Overview

The ISL9305IRTHWLNCZ-T is a quad-output Power Management IC (PMIC) from Renesas Electronics Corporation. It integrates two step-down buck regulators and two linear LDOs, designed for low-voltage microprocessor applications. The device operates with an input voltage range of 1.5V to 5.5V and features a switching frequency of 3MHz. Each step-down converter supports up to 1.5A load current, while the LDOs provide stable regulation. The component is housed in a 16-TQFN package and supports I2C interface control for dynamic power saving.

Feature Summary

• Integrates dual high-current step-down converters and dual low-input LDOs for comprehensive power management
• Supports I2C interface for on-the-fly slew rate control and dynamic voltage scaling
• Optimized for low-voltage microprocessors using single Li-Ion or battery sources

Applications

• Low-voltage microprocessor power systems
• Single Li-Ion battery powered devices
• Portable electronic equipment requiring efficient power conversion

Procurement Notes

Verify component status as obsolete. Confirm availability through authorized distributors only. Check RoHS compliance and MSL ratings before integration. Ensure proper handling for moisture-sensitive levels during assembly.

Selection Notes

Select this PMIC for designs requiring integrated buck and LDO outputs in a compact footprint. Verify input voltage compatibility with 1.5V-5.5V range. Consider thermal performance under maximum load conditions for both buck and LDO channels.

Part Context

Part of the ISL9305 family of mini-PMICs. Designed for space-constrained applications needing multiple regulated rails from a single source. Replaces discrete regulator solutions with integrated functionality.

Replacement Considerations

Check for pin-compatible alternatives if sourcing new production units. Verify electrical parameters match original design requirements when substituting.
