ISL91107IRTNZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL91107IRTNZ is a high-efficiency buck-boost switching regulator IC manufactured by Renesas Electronics Corporation. It features integrated 4.25A switches and operates within an input voltage range of 2.7V to 5.5V, delivering a fixed 3.3V output at up to 2A. The device utilizes a 20-WFQFN exposed pad package for surface mount installation. It supports a switching frequency of 2.5MHz and functions reliably across an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates high-current 4.25A power switches for efficient energy conversion
• Operates in both step-up and step-down modes to accommodate varying input voltages
• Utilizes a compact 20-pin QFN package with exposed thermal pad

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered devices requiring stable voltage regulation
• Single-cell lithium-ion battery systems
• Industrial control modules with fluctuating supply lines

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'RTNZ' confirms the tube packaging format and lead-free RoHS compliance status. Confirm the manufacturer is Renesas Electronics Corporation, as Intersil branding may appear on legacy documentation. Ensure the component matches the 20-WFQFN physical dimensions and pinout configuration required for your PCB layout before finalizing orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require handling input voltages both above and below the desired output level. The integrated 4.25A switches provide significant current headroom compared to lower-rated alternatives. Consider the 20-WFQFN package size constraints and thermal dissipation requirements associated with the exposed pad design during the initial schematic capture phase.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9110 family of single-inductor buck-boost regulators. While other variants like the ISL9110 offer 2A switch ratings, the ISL91107 specifically integrates higher current capability. The family shares common control logic but differs in power stage specifications and package options such as TDFN or WFQFN configurations.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ISL91107IRTNZ-T7A serves as a tape-and-reel alternative to the tube-packaged RTNZ version. Both share identical electrical characteristics and pinouts. Verify that the reel quantity matches production needs if transitioning from tube to tape packaging.
