ISL8024AIRTAJZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8024AIRTAJZ is a synchronous buck switching regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.7 V to 5.5 V and delivers a maximum output current of 4 A. The adjustable output voltage spans from 600 mV to 5.5 V. The device supports a programmable switching frequency between 500 kHz and 4 MHz. It is housed in a 16-lead QFN package with an exposed pad (QFN-EP-16) designed for surface-mount installation. The component functions reliably across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AJZ' against official Renesas documentation to confirm the exact tape-and-reel or tray packaging configuration, as suffixes often dictate shipping units rather than electrical function. Ensure compliance with RoHS3 standards and check Moisture Sensitivity Level (MSL) ratings prior to assembly. Confirm that the supplier provides valid traceability data for the 16-WFQFN EP package to maintain quality assurance protocols.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 4 A output capacity is required within a 2.7 V to 5.5 V input window. The adjustable frequency feature allows optimization for either size or noise performance. Compare against the ISL8025 series if higher current capability is needed, or the ISL8023 series for reduced load requirements. Ensure the thermal design accommodates the QFN-EP-16 package constraints for the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context
