Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the QFN-32 package dimensions match your PCB footprint requirements. Ensure compatibility with the 2.7 V to 5.5 V input voltage range for your target application. Check for any specific humidity sensitivity handling requirements during assembly. Validate that the I2C address settings do not conflict with other devices on the bus.

Selection Notes

Select this PMIC when a single solution is needed to power complex systems with multiple voltage rails. It is suitable for designs requiring both high-efficiency buck conversion and precise LDO regulation. Consider the QFN-32 package size constraints and thermal dissipation needs. Evaluate the need for USB interface support alongside standard digital control. Ensure the operating temperature range meets the environmental conditions of the final product.
