ISL91107IIAZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL91107IIAZ-T is a high-efficiency synchronous buck-boost switching regulator manufactured by Renesas Electronics. It operates with an input voltage range of 1.8 V to 5.5 V and provides an adjustable output voltage from 1 V to 5.2 V. The device supports up to 2 A output current and features a fixed switching frequency of 2.5 MHz. It utilizes a WLCSP-15 package with dimensions of 2.15 mm x 2.15 mm and a height of 0.3 mm. Quiescent current is specified at 45 μA, and the operating temperature range extends from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the WLCSP-15 footprint matches your PCB design constraints. Ensure compatibility with the 2.5 MHz switching frequency regarding EMI requirements. Check RoHS compliance status through official manufacturer documentation before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-stage buck-boost solution is required for inputs near or below the target output voltage. The WLCSP package suits designs where board area is limited compared to TQFN alternatives. Consider the 2 A current limit against peak load demands. Verify thermal performance within the specified ambient temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL91107 series of high-efficiency regulators. It shares functional similarities with other members like the ISL91107IRTAZ but differs in package type. The series targets applications demanding small form factors and wide input voltage ranges without sacrificing efficiency.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ISL91107IRTAZ offers identical electrical specifications but uses a TQFN-EP-20 package. Substitution requires PCB layout redesign due to different pinout and physical dimensions. No direct pin-to-pin compatible alternative exists in the same package.
