ISL8016IR12Z

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8016IR12Z is a synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 1.2 V at a maximum continuous output current of 6 A. The device supports adjustable switching frequencies from 500 kHz to 4 MHz, enabling optimization for efficiency or component size. It features low quiescent current and is housed in a 20-lead QFN package with an exposed pad, suitable for surface mount applications across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'IR12Z' confirms the fixed 1.2 V output variant, as the base ISL8016 series includes adjustable and other fixed voltage options. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Ensure the 20-QFN package footprint matches your PCB layout guidelines. Check for any recent product change notices regarding manufacturing sites or labeling updates.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a stable 1.2 V rail is required at up to 6 A from a 3.3 V or 5 V source. The adjustable frequency feature allows trade-offs between inductor size and EMI performance. Consider the thermal performance of the 20-QFN package under full load conditions. Verify that the input voltage remains within the 2.7 V to 5.5 V operational window during all system states.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL8016 series belongs to Renesas's portfolio of high-current synchronous buck regulators. This family is designed for applications requiring efficient power management in compact form factors. The ISL8016IR12Z specifically denotes the fixed 1.2 V output version within the broader ISL8016 lineup, which also includes adjustable and other fixed voltage variants.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other ISL8016 variants with different output voltages if the voltage requirement changes, such as ISL8016IR18Z for 1.8 V or ISL8016IR33Z for 3.3 V. Cross-referencing with newer Renesas PMIC families may be necessary for updated features or availability.
