ISL6556BCB

Special Purpose Regulators Overview

The ISL6556BCB is a specialized voltage regulator controller designed for Intel VR10.x applications. It operates with an input voltage range of 3V to 12V and provides four independent outputs. The output voltage is adjustable from 0.84V to 1.6V. The device functions within a commercial temperature range of 0°C to 70°C and is housed in a 28-SOIC package.

Special Purpose Regulators Feature Summary

• Optimized multi-phase PWM control architecture
• Integrated 6-bit digital-to-analog converter (DAC)
• Programmable internal temperature compensation

Special Purpose Regulators Applications

• Intel VR10.x processor power regulation
• Multi-phase voltage regulator modules (VRMs)

Special Purpose Regulators Procurement Notes

Verify component status as the ISL6556BCB series is listed as obsolete or discontinued by Renesas Electronics. Confirm availability through authorized distributors or surplus channels, noting that standard lead times may not apply. Ensure compatibility with existing board designs before sourcing replacement inventory.

Special Purpose Regulators Selection Notes

Select this component for legacy Intel VR10.x designs requiring a dedicated multi-phase controller. Consider the integrated DAC and temperature compensation features for precise voltage tracking. Evaluate alternative modern controllers if new design-in opportunities exist due to the component's discontinued status.

Special Purpose Regulators Part Context

The ISL6556BCB belongs to the Intersil (now Renesas) ISL6556 family of optimized multi-phase PWM controllers. These devices are engineered specifically for high-performance CPU power delivery systems, offering integrated management features to simplify VRM implementation for Intel processors.
