Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Renesas Electronics Corporation to ensure authenticity. Check RoHS compliance status via official documentation before integration. Ensure the DFN-EP-12 footprint matches your PCB layout requirements precisely.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1 A output capability is required within a compact form factor. The 570 kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 40 V input rating if the source voltage exceeds standard 12 V or 24 V levels. Evaluate the 80 uA quiescent current against system standby power constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL85410 family of synchronous buck regulators. It shares architectural similarities with other members like the ISL85418 but differs in output current capacity. The FRZ suffix typically denotes lead-free and RoHS-compliant manufacturing standards. It serves as a core power management IC for converting higher bus voltages to logic-level supplies.
