ISL8016IR25Z

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8016IR25Z is a synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It delivers a fixed 2.5V output at up to 6A with an input voltage range of 2.7V to 5.5V. The device operates within a switch frequency range of 500 kHz to 4 MHz and supports adjustable frequencies for optimization. It features low quiescent current, cycle-by-cycle current limiting, and thermal shutdown protection. The component is housed in a 20-lead QFN package (3x4 mm) with an exposed pad for thermal management.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronics requiring efficient power conversion
• Industrial control systems with single-supply inputs
• Communication equipment power distribution networks
• Embedded computing modules needing stable 2.5V rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'IR25Z' matches the required fixed 2.5V output variant. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check datasheet for recommended external component values to ensure stability at the selected operating frequency and load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 2.5V output is needed with up to 6A capability. Ensure the input supply stays within the 2.7V to 5.5V range. Consider the 20-QFN package size constraints and thermal dissipation needs. Compare against adjustable variants if voltage flexibility is required instead of a fixed rail.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the ISL8016 family of high-efficiency synchronous buck regulators. Shares common pinout and control architecture with other ISL8016 variants differing only in output voltage settings or packaging options. Designed for applications requiring small footprint and high performance from single-cell lithium-ion sources.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other ISL8016 variants with different fixed outputs (e.g., ISL8016IR18Z for 1.8V, ISL8016IR33Z for 3.3V) if voltage adjustment is possible. Verify pin compatibility and thermal characteristics before swapping.
