ISL8088IRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

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

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification for high efficiency
• Compact 3x3 mm DFN-EP package design

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring dual power rails
• Embedded systems with low-voltage logic requirements
• Industrial control modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the standard tray configuration found in other variants like ISL8088IRZ. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for End-of-Life notices or production discontinuation announcements from the manufacturer to ensure long-term supply availability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated outputs are required from a single input source within the 2.75 V to 5.5 V range. The 800 mA per channel rating suits moderate load applications. Ensure the PCB layout accommodates the 10-lead DFN-EP footprint and thermal pad requirements for adequate heat dissipation at full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL8088 series of synchronous buck converters. It is distinct from single-channel regulators and higher-current multi-phase controllers. The device integrates internal MOSFETs, simplifying the external component count compared to discrete solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include the ISL8088IRZ (tray package) if reel packaging is not strictly required. Verify pinout compatibility and electrical specifications before cross-referencing with other dual-channel regulators.
