ISL6556BCBZ Description

Short technical summary and product information.

The ISL6556BCBZ from Renesas is an optimized multi-phase PWM controller featuring a 6-bit DAC and programmable internal temperature compensation for VR10.X applications. This controller drives up to 4 synchronous-rectified buck channels in parallel, utilizing interleaved timing to enhance ripple frequency and reduce current ripple. It employs rDS(ON) current sensing for adaptive voltage positioning, channel-current balancing, and overcurrent protection.

Key electrical specifications include a voltage range of 0.8375V to 1.600V in 12.5mV steps and a 4-output configuration. The operating temperature range is from 0°C to 70°C. The device supports differential remote voltage sensing for accurate ground potential elimination and features Dynamic-VID™ technology for seamless on-the-fly VID changes. An integrated shunt regulator allows for 5V or 12V biasing.

Packaged in a 28-SOIC (0.295", 7.50mm Width) surface mount configuration, the ISL6556BCBZ is suitable for applications requiring precise core voltage regulation. It also includes overvoltage protection and a threshold enable function for precise sequencing.

This component is RoHS3 compliant, has an MSL of 1, and is REACH unaffected, though these compliance statuses are unverified.
