ISL85418FRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL85418FRZ-T is a synchronous buck regulator from the Renesas ISL85418 series, designed for high-efficiency power conversion. It operates with an input voltage range of 3 V to 40 V and delivers up to 800 mA output current. The adjustable output voltage spans from 600 mV to 34 V. Operating at a fixed switching frequency of 570 kHz, it features low quiescent current of 4 uA in shutdown mode. The device supports operation temperatures from -40°C to +125°C and is housed in a DFN-EP-12 package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when ordering. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the manufacturer part number against authorized distributor lists to guarantee authenticity and traceability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring moderate output current within a wide input voltage window. The fixed 570 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the DFN-EP-12 package constraints regarding PCB thermal relief requirements during layout design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL85418 family of synchronous buck regulators manufactured by Renesas Electronics. It shares architectural similarities with other members like the ISL85410 but offers higher current capacity. The series targets general-purpose power management needs in compact form factors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include ISL85410FRZ for lower current needs or ISL85415FRZ for 500mA applications. Verify pin compatibility and thermal performance before swapping.
