Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL8025AIRTAJZTR5666

ISL8025AIRTAJZTR5666

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8025AIRTAJZTR5666 is a synchronous buck regulator from the ISL8025A series, manufactured by Renesas/Intersil. It delivers 5A continuous output current with an input voltage range of 2.7V to 5.5V and adjustable output from 600mV to 5.5V. The device operates at a default switching frequency of 2MHz, adjustable up to 4MHz, using a TQFN-EP-16 package. It features low ON-resistance FETs (36mΩ P-channel high-side, 13mΩ N-channel low-side) for high efficiency and includes internal protection against overcurrent, overtemperature, and overvoltage.

Voltage Regulators - DC DC Switching Regulators Feature Summary

High-efficiency synchronous buck topology with integrated low ON-resistance power FETs
Adjustable switching frequency from 500kHz to 4MHz with external synchronization capability
Integrated fault protection including hiccup mode current limiting, overtemperature, and overvoltage safeguards

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in portable electronics
Power management for embedded systems requiring stable 5V or lower rails
Industrial control boards needing compact DC/DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'TR5666' against official Renesas documentation, as standard datasheets typically list 'ISL8025AIRTAJZ'. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Ensure the supplier provides valid traceability documents matching the manufacturer's part identification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 5A synchronous buck converter with a 2.7V–5.5V input range is required. The 2MHz default frequency offers a balance between size and efficiency. Consider the TQFN-EP-16 package for thermal performance. Verify that the adjustable frequency range meets system noise constraints and that external synchronization is needed if multiple converters operate in proximity.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL8025 family of highly efficient monolithic synchronous step-down DC/DC converters. The ISL8025A variant specifically defaults to 2MHz operation, distinguishing it from the base ISL8025 which defaults to 1MHz. The family is pin-to-pin compatible with ISL8023 and ISL8024, facilitating design upgrades within the same footprint constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Officially documented pin-compatible replacements include the ISL8023 and ISL8024. Verify that the substitute part supports the required 5A output current and matches the input voltage range of 2.7V to 5.5V. Check if the alternative’s default switching frequency aligns with existing passive component values.
