ISL78236ARZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78236ARZ-T is a dual-channel synchronous step-down switching regulator 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, allowing for the use of compact external components. Key internal features include integrated power MOSFETs and a dedicated current sharing regulator that ensures balanced load distribution between the two channels. This configuration supports high-efficiency power conversion in space-constrained applications requiring multiple voltage rails.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific ordering suffix and package variant against the official Renesas datasheet to ensure compatibility with your PCB footprint and thermal management strategy. Confirm that the required input voltage range aligns with your system's power supply specifications. Check for any recent lifecycle status updates or recommended replacement parts from the manufacturer before finalizing component selection for production.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for generating two distinct regulated voltages from a single input source. The fixed 2.25MHz frequency is suitable for designs prioritizing board space over ultra-low noise. Ensure that the total current demand does not exceed the combined capability of both channels while maintaining adequate thermal dissipation through proper PCB layout techniques.
