Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL78233ARZ-T7A

ISL78233ARZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78233ARZ-T7A is an automotive-grade synchronous buck regulator designed for high-efficiency power conversion. It features a wide input voltage range of 2.7V to 5.5V and delivers up to 4A of output current. The device integrates low ON-resistance P-channel (35mΩ) and N-channel (11mΩ) FETs to minimize conduction losses. It supports adjustable output voltages starting from 0.6V and operates within a junction temperature range of -40°C to 150°C. Packaged in a 16-WFQFN exposed pad, it ensures reliable performance in demanding automotive environments.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T7A' indicates tape and reel packaging when ordering. Confirm that the component meets AEC-Q100 standards for your target application. Ensure the 16-WFQFN package footprint matches your PCB layout requirements. Check for RoHS compliance documentation if required by your supply chain regulations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, high-current solution is needed for 5V automotive buses. The integrated FETs simplify thermal management compared to discrete designs. Consider the 4A capability for powering multiple downstream loads or high-drain peripherals. Verify input voltage stability within the 2.7V to 5.5V window during cold crank conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL78233 family of synchronous buck regulators. It shares architectural similarities with other automotive-grade power ICs from Renesas but is distinct in its specific current rating and package configuration. The 'ARZ' designation typically denotes automotive qualification and lead-free composition.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include the ISL78233ARZ in tray packaging or the ISL78233ARZ-T in standard tape and reel. Verify pinout compatibility before replacing. Cross-reference electrical parameters such as switching frequency and thermal resistance to ensure equivalent performance.
