Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix JZ against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS compliance status and check for End-of-Life notices, as Intersil products transitioned to Renesas. Ensure the supplier provides valid traceability documentation for this discontinued or transitioning component series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 1.5V output is required from a 2.7V to 6V input source. The 4.3MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 500mA load requirement fits within the thermal limits of the 6-UTDFN package for the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the ISL9104 family of low IQ synchronous buck converters. It was originally developed by Intersil before the company's acquisition by Renesas Electronics. The product line focuses on providing high efficiency in small form factors for portable applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official Renesas documentation for direct cross-references. Alternative packages such as IRUBZ may offer different thermal profiles. Verify compatibility with existing PCB footprints if substituting with other ISL9104 variants.
