ISL95833HRTZ

Special Purpose Regulators Overview

The ISL95833HRTZ is a dual 2+1 PWM controller from the Robust Ripple Regulator (R3) series, designed for Intel IMVP-7 and VR12 notebook CPU applications. It operates with an input voltage range of 4.75V to 5.25V and provides adjustable output voltages from 250mV to 1.52V. The device supports up to 60A output current and functions within a temperature range of -10°C to +100°C. Packaged in a 32-QFN (4x4mm) exposed pad surface-mount enclosure, it is currently classified as obsolete by the manufacturer.

Special Purpose Regulators Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability is restricted to existing stock or surplus channels only. Buyers must confirm end-of-life status and potential obsolescence risks before procurement. Alternative sourcing should prioritize verified distributors capable of providing authenticity guarantees for legacy inventory.

Special Purpose Regulators Selection Notes

Engineers selecting this part must account for its obsolete status and limited long-term supply chain security. Design-in decisions should consider the transition to newer generations within the R3 family or compatible successors that maintain IMVP-7/VR12 compliance. Thermal management requirements align with the specified -10°C to +100°C operating range and 32-QFN package constraints.
