ISL6410IU-T5K

Voltage Regulators - DC DC Switching Regulators Overview

The ISL6410IU-T5K is a synchronous buck switching regulator IC manufactured by Intersil. It operates with an input voltage range of 3 V to 3.6 V and delivers a programmable output voltage between 1.2 V and 1.8 V. The device provides a maximum output current of 600 mA through a single output channel. It functions at a fixed switching frequency of 860 kHz. The component is housed in a 10-lead MSOP package with a width of 3.00 mm. It supports surface mount installation and operates within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix T5K against the required reel quantity, as packaging formats vary. Confirm RoHS compliance status directly from the manufacturer datasheet before integration. Check for obsolescence notices or lifecycle changes, as Intersil products may have transitioned to Renesas Electronics. Ensure the MSOP-10 footprint matches the design layout constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for 3V input applications. The 600mA output capability suits moderate load requirements. Compare the 860kHz frequency against noise sensitivity requirements in the target system. Verify that the 1.2V to 1.8V programmable range covers all downstream logic levels. Consider the thermal performance of the MSOP package under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL6410 series of synchronous buck regulators. It shares architectural similarities with variants like the ISL6410AIUZ, which supports higher 5V inputs. The IU-T5K designation specifically indicates the industrial temperature grade and tape-and-reel packaging format. It serves as a power management integrated circuit (PMIC) within the broader portfolio of DC-DC switching regulators.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ISL6410IUZ is a pin-compatible variant available in tube packaging rather than tape-and-reel. The ISL6410AIUZ offers similar functionality but requires a 4.5V to 5.5V input supply, making it electrically incompatible for 3V systems without hardware modification.
