ISL6410IU-TK

Voltage Regulators - DC DC Switching Regulators Overview

The ISL6410IU-TK is a synchronous buck switching regulator IC manufactured by Intersil. It features a programmable output voltage range of 1.2V, 1.8V, and 3.3V with a maximum continuous output current of 600mA. The device operates from an input voltage range of 4.5V to 5.5V and integrates a fixed internal switching frequency of 750kHz. Designed for surface-mount applications, it utilizes a 10-MSOP package (10-TFSOP, 10-MSOP, 3.00mm wide). The component supports positive output configuration and functions within an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure that the procurement channel provides valid traceability records, as this component may be subject to end-of-life status or obsolescence notices. Cross-reference the part number with current Renesas Electronics catalogs to validate availability and compliance with environmental standards such as RoHS restrictions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Evaluate the thermal performance requirements of the application against the limitations of the 10-MSOP package. Confirm that the system's input voltage remains strictly within the specified 4.5V to 5.5V window to prevent operational instability. Assess the load current demands to ensure they do not exceed the 600mA limit under all operating conditions and temperature ranges.

Voltage Regulators - DC DC Switching Regulators Part Context
