ISL9305IRTHWCNYZ-T7A

Overview

The ISL9305IRTHWCNYZ-T7A is a mini Power Management IC (mini-PMIC) manufactured by Renesas Electronics Corporation. It features a quad output configuration comprising two step-down converters and two low-input linear regulators (LDOs). The switching frequency for the buck converters is 3MHz. The device supports an input voltage range of 1.5V to 5.5V. Output currents are specified as 800mA for the first two outputs, 800mA for the third, and 350mA for the fourth. It is housed in a 16-TQFN package with dimensions of 4x4 mm.

Feature Summary

• Integrates dual step-down converters and dual low-input LDOs into a single compact package.
• Operates with a fixed 3MHz switching frequency for the DC-DC converters.
• Supports I2C compatible interface for control and monitoring.

Applications

• Powering low-voltage portable electronic devices
• Smart earbuds case chargers
• Mobile phone peripheral power management

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix 'WCNYZ' matches your bill of materials requirements. Check for recent Product Change Notices regarding label updates or assembly facility changes. Ensure ESD handling protocols are followed during storage and installation. Validate that the 16-TQFN footprint aligns with your PCB design guidelines.

Selection Notes

Select this component when a highly integrated solution is required for space-constrained designs. It combines both switching and linear regulation capabilities. Consider the 3MHz frequency for smaller external passive components. Evaluate the total current capacity against load requirements. Verify compatibility with system control interfaces if I2C functionality is utilized.
