ISL6273IRZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL6273IRZ is a single-output synchronous buck converter manufactured by Renesas Electronics Corporation, formerly Intersil. It integrates power switches and operates with an input voltage range of 2.7 V to 5.5 V. The device provides a maximum output current of 1.2 A and supports adjustable output voltages from 800 mV to 5.5 V. It features a fixed switching frequency of 1.5 MHz and functions within an operating temperature range of -40°C to +85°C. The component is housed in a DFN-EP-10 surface-mount package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the End-of-Life (EOL) status before procurement, as the product lifecycle is listed as discontinued. Confirm availability through authorized distributors or secondary markets, noting that supply may be restricted. Ensure the specific DFN-EP-10 package variant matches the design requirements. Check for RoHS compliance documentation if required for the target market regulations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a simple, integrated step-down solution with moderate current demands up to 1.2 A. It is suitable for systems powered by single-cell lithium-ion batteries or 5V rails where space is constrained. Consider the fixed switching frequency when designing external passive components. Verify thermal performance given the small footprint and integrated switch topology.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL6273 belongs to the Intersil/Renesas portfolio of low-power switching regulators designed for portable electronics. It represents a class of highly integrated DC-DC converters that combine control logic and power stages into a single package. This approach reduces the overall bill of materials and PCB area compared to discrete solutions, targeting mobile and handheld device manufacturers.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

As the part is marked as End-of-Life, direct substitutes must be sourced from secondary suppliers or equivalent newer generations from Renesas. Verify pin compatibility and electrical specifications against alternative single-output buck converters with similar 1.2 A current ratings and 1.5 MHz frequencies.
