ISL6410AIUZ-TK

Voltage Regulators - DC DC Switching Regulators Overview

The ISL6410AIUZ-TK is a synchronous current-mode PWM buck regulator manufactured by Intersil (Renesas). It operates from a 5.0V ±10% input voltage range and delivers up to 600mA of continuous output current. The device integrates high-side and low-side power FETs within a compact MSOP-10 package. Key electrical specifications include an 860kHz switching frequency, programmable output voltages ranging from 1.2V to 3.3V, and a typical load regulation of 1.5%. It functions within an ambient temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status as datasheets may vary by revision. Check for End-of-Life notices or obsolescence declarations prior to procurement. Ensure the supplier provides valid traceability documents for this discontinued component series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 5V input source is available and a single regulated output between 1.2V and 3.3V is required. The 600mA current limit suits low-power digital logic applications. Consider the MSOP-10 package constraints for thermal dissipation. Verify that the external compensation network meets stability requirements for the chosen output capacitance.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL6410 family of synchronous DC-DC converters designed for portable electronics. It serves as a complete step-down solution for powering sensitive digital components. The AIUZ variant specifically targets 5V input systems, distinguishing it from the ISL6410 series designed for 3.3V inputs. The TK suffix indicates reel packaging.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate generic synchronous buck regulators with similar 5V input and 600mA output capabilities if direct replacements are required.
