ISL78236ARZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78236ARZ-T7A is a dual synchronous buck switching regulator IC manufactured by Renesas Electronics Corporation. It integrates two independent channels, each capable of delivering up to 3A of output current. The device operates with a fixed switching frequency of 2.25MHz and supports an input voltage range from 2.85V to 6V. It features adjustable output voltages starting from 1.2V. The component is housed in a 24-pin VFQFN package with an exposed pad for thermal management.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix T7A against official datasheets to confirm reel quantity and tape specifications. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 24-VFQFN package dimensions match your PCB footprint requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring two isolated or non-isolated low-voltage outputs from a single input source. It is suitable for applications where space constraints favor integrated solutions over discrete controllers. Consider the 2.25MHz frequency for balancing component size and efficiency. Ensure the thermal design accommodates the 3A per channel capability within the VFQFN package limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL78236 series of dual synchronous buck regulators. It is designed for applications needing compact, efficient power delivery. The series is commonly used in portable electronics and industrial control systems where multiple voltage rails are necessary.
