ISL9110SIINZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9110SIINZ-T is a synchronous buck-boost switching regulator IC manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 1.8 V to 5.5 V and provides a positive adjustable output voltage up to 5.2 V with a maximum output current of 1.2 A. The device utilizes a fixed switching frequency of 2.5 MHz and features synchronous rectification for high efficiency. It is housed in an 8-SOIC package (0.154 inch width) and supports operation across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'IINZ' against official Renesas documentation to confirm pinout compatibility and thermal characteristics. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Ensure ordering quantities align with standard reel or tray packaging requirements specified by the distributor. Validate that the 8-SOIC package dimensions match the target PCB footprint constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an adjustable output voltage is required rather than a fixed rail. The 1.2 A current rating suits moderate load applications where space efficiency is prioritized over high-power delivery. Consider the 2.5 MHz frequency trade-off between component size and electromagnetic interference. Verify that the input voltage profile remains within the 1.8 V to 5.5 V operational window for reliable regulation.
