ISL9305IRTHWCNYZ-T

Overview

The ISL9305IRTHWCNYZ-T is a mini-PMIC from Renesas Electronics featuring four independent regulators: two 3MHz step-down converters and two low-input LDOs. It operates on a 1.5V to 5.5V supply within -40°C to 85°C. Output specifications include 1.5V/800mA, 2.5V/800mA, and 3.3V/350mA. Packaged in a 16-TQFN (4x4) with an exposed pad, it supports surface mount installation. The device complies with RoHS3 standards and has an MSL rating of 3.

Feature Summary

• Integrates dual high-frequency buck converters and dual low-input LDOs for compact power solutions
• Provides independent voltage regulation across four distinct output channels
• Designed for efficient power management in space-constrained electronic applications

Applications

• Portable consumer electronics requiring multi-rail power distribution
• Embedded systems utilizing low-voltage logic and analog components
• Industrial control modules operating within specified temperature ranges

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required electrical and thermal specifications. Check current availability status as this part may be subject to end-of-life notices. Ensure proper handling procedures are followed due to moisture sensitivity level ratings during storage and assembly processes.

Selection Notes

Select this component when a single IC solution is needed to replace multiple discrete regulators. Evaluate the total output current requirements against the specific channel limits. Consider the 3MHz switching frequency for minimizing external passive component size. Verify that the input voltage range aligns with the system's power source capabilities.
