ISL9307IRTWCWNZ-T7A

Overview

The ISL9307IRTWCWNZ-T7A is a quad-output mini-PMIC integrating two synchronous buck converters and two low-dropout linear regulators. It operates with an input voltage range of 1.5V to 5.5V. Output 1 and Output 2 provide adjustable voltages from 0.8V to 5.5V with a maximum current of 1.5A each. Output 3 is fixed at 2.8V with 300mA capability, while Output 4 supports 0.8V to 5.5V at 300mA. The device utilizes a 3MHz switching frequency and is housed in a 16-TQFN (4x4) package.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for compact power solutions
• Supports wide input voltage range suitable for single-cell lithium battery applications
• Features high-frequency operation to minimize external component size

Applications

• Portable electronic devices requiring multi-rail power distribution
• Smartphones and mobile communication equipment
• Handheld computing devices and tablets

Procurement Notes

Verify the specific suffix WCW against official Renesas documentation to confirm pinout and thermal pad configuration. Confirm end-of-life status and availability of qualified replacement components through authorized channels before finalizing design implementation.

Selection Notes

Select this component when space-constrained designs require multiple regulated rails from a single IC. Ensure the total output current requirements do not exceed the specified limits for each regulator channel. Verify that the operating temperature range meets the environmental conditions of the target application.
