ISL9305IRTHBFNCZ-T

Overview

The ISL9305IRTHBFNCZ-T is a quad output PMIC from Renesas, integrating two buck converters and two LDOs in a 16-TQFN package. It operates with an input voltage range of 1.5V to 5.5V at a switching frequency of 3MHz. Output 1 provides 1.5V at 800mA, Output 2 provides 2.5V at 800mA, and Output 3 provides 3.3V at 350mA. The device supports surface mount installation and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates dual step-down and dual linear regulators for compact power solutions
• Features high-frequency 3MHz switching operation
• Includes integrated current sensing capabilities

Applications

• Portable electronic devices requiring multi-rail power
• Embedded systems with mixed analog and digital loads
• Industrial control modules

Procurement Notes

Verify the specific suffix 'IRTBFNCZ' against official Renesas documentation to confirm pinout and thermal pad configuration. Confirm RoHS3 compliance status as required by project specifications. Check for End-of-Life (EOL) notifications or last-time-buy dates prior to finalizing procurement plans.

Selection Notes

Select this component when a single IC solution is needed for low-voltage applications requiring both efficient DC-DC conversion and low-noise LDO regulation. Ensure the 800mA output current capability meets the peak load requirements of the target circuit rails.

Part Context

This part belongs to the ISL9305 family of quad-output power management ICs designed for space-constrained applications. It consolidates multiple power stages into a single small footprint, reducing the overall bill of materials and board area compared to discrete regulator implementations.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Verify that any alternative maintains identical pin compatibility and electrical characteristics.
