ISL80015AIRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL80015AIRZ-T7A is a compact synchronous buck converter manufactured by Renesas Electronics Corporation. It provides a single positive adjustable output voltage ranging from 0.6V to 5.5V with a maximum output current of 1.5A. The device operates with an input voltage range of 2.7V to 5.5V and features a fixed switching frequency of 2MHz. It utilizes pulse width modulation (PWM) for fast transient response and supports 100% duty cycle operation at lower frequencies. The component is housed in an 8-WFDFN exposed pad package and is rated for operating temperatures between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix T7A against official Renesas documentation to confirm reel packaging specifications. Confirm end-of-life status as multiple sources indicate discontinuation or last-time buy status. Ensure compatibility with existing PCB footprints for the 8-WFDFN package. Check for moisture sensitivity level requirements during storage and handling. Validate that the 1.5A current rating meets system peak load demands without derating issues.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a small form factor synchronous buck regulator is required for inputs up to 5.5V. Consider the 2MHz switching frequency for minimizing inductor size compared to lower-frequency alternatives. Evaluate the 1.5A output capability against maximum load currents including ripple margins. Assess thermal performance needs given the exposed pad package design. Compare against newer Renesas ISL8002 series if higher current capacity is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL80015 family of compact synchronous buck converters from Renesas. It shares architectural similarities with other members like the ISL80015AIRZ-T but differs in packaging and tape-and-reel configuration. The series targets applications demanding high efficiency in minimal board space. Renesas continues to support legacy Intersil products through this lineage.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ISL8002AIRZ-T7A offers similar functionality with increased 2A output current capability. Verify pin-to-pin compatibility before substitution. Check updated datasheets for any changes in thermal characteristics or control loop stability. Ensure the replacement part meets the same temperature and voltage specifications.
