ISL8026AFRTAJZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8026AFRTAJZ is a synchronous buck regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.5 V to 5.5 V and delivers up to 6 A of output current. The adjustable output voltage spans from 600 mV to 5.5 V. Key electrical parameters include a switching frequency of 1 MHz, a maximum static current of 50 uA, and a typical operating supply current of 5 uA. The device supports shutdown functionality and is housed in a TQFN-EP-16 package suitable for surface mount installation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'FRTAJZ' against official Renesas documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with RoHS directives and check moisture sensitivity levels prior to assembly. Confirm that the TQFN-EP-16 package aligns with your PCB footprint requirements and thermal management strategy.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 6 A output current capability is required within a 2.5 V to 5.5 V input window. The adjustable output voltage range makes it suitable for various logic levels. Consider the 1 MHz default switching frequency for balancing efficiency and component size. Evaluate thermal performance given the TQFN-EP-16 package constraints for your specific application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL8026 series of synchronous buck regulators. It shares architectural similarities with the ISL8025 but offers higher current capacity. The series is designed for applications demanding high efficiency and small form factors. Renesas integrates these controllers into broader power management portfolios for industrial and consumer electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ISL8025 is pin-to-pin compatible but provides only 5 A output current. Verify if the reduced current rating meets your design requirements before substitution. Other members of the ISL802x family may offer different current ratings or features.
