ISL8088IRZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8088IRZ is a dual-channel synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.75 V to 5.5 V and provides adjustable output voltages from 600 mV to 5.5 V. Each channel delivers up to 800 mA of output current at a fixed switching frequency of 2.25 MHz. The device is housed in a 10-lead DFN package (3x3 mm) with an exposed pad, designed for surface mount installation. It functions within an ambient temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for recent Product Change Notifications regarding manufacturing site updates or material composition changes. Ensure storage conditions comply with moisture sensitivity level requirements before reflow soldering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a dual-output solution is required within a small footprint constraint. The fixed 2.25 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the total current demand per channel does not exceed 800 mA. Consider thermal dissipation capabilities of the 10-DFN package relative to the expected power loss under maximum load conditions.
