ISL6269ACRZ-T

DC DC Switching Controllers Overview

The ISL6269ACRZ-T is a single-phase synchronous-buck PWM controller designed for high-performance notebook applications. It utilizes Intersil's Robust Ripple Regulator R3 Technology to deliver superior transient response and stability. The device operates with an input supply voltage range of 5 V to 25 V. It features a digital soft-start function with a duration of 1.5 ms, enabling startup into prebiased output voltages. The output voltage is programmable via an external resistor divider.

DC DC Switching Controllers Procurement Notes

Verify component authenticity as the ISL6269ACRZ series is listed as no longer manufactured by Renesas Electronics Corporation. Confirm availability status with suppliers, as stock may be depleted. Ensure the specific suffix matches the required packaging type, such as cut tape, and validate moisture sensitivity handling requirements during procurement and storage.

DC DC Switching Controllers Selection Notes

Select this controller for single-phase synchronous buck applications requiring robust ripple regulation technology. It is suitable for systems operating within a 5 V to 25 V input range. Consider the 1.5 ms digital soft-start capability if prebiased output startup is required. Verify compatibility with notebook power architecture requirements before integration.

DC DC Switching Controllers Part Context

This component belongs to the ISL6269A family of high-performance notebook PWM controllers from Renesas Electronics Corporation (formerly Intersil). The family focuses on single-phase synchronous buck solutions utilizing proprietary R3 technology. The part is distinct from multi-phase or dual-output VR controllers found in other Renesas product lines.

DC DC Switching Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is discontinued, verify functional equivalence with current Renesas offerings or alternative manufacturers based on specific electrical parameters and pinout compatibility.
