Datasheet Summary
Powered by GS/AI

The ISL6569CBZ is a multi-phase PWM controller designed for core-voltage regulation, capable of driving two interleaved synchronous-rectified buck-converter channels in parallel. This interleaving technique enhances ripple frequency, which in turn reduces input and output ripple currents, leading to lower component costs and a more compact design. Key features include active channel current balancing using precision rDS(ON) sensing, a high-bandwidth error amplifier for output voltage regulation, and a programmable reference offset. The controller supports a 5-bit VID input for dynamic voltage identification, allowing output voltage adjustments from 0.800V to 1.550V in 25mV increments. It also offers optional active voltage positioning to minimize output capacitor size and cost. The ISL6569CBZ incorporates robust protection mechanisms, including over-voltage protection that activates a crowbar function, under-voltage detection, and over-current protection with a hiccup-mode response. The device operates within a temperature range of 0 to 70¬8C and is available in a 24-lead SOIC package, compliant with RoHS standards. This controller is suitable for applications such as voltage regulation for AMD Hammer family processors and low output voltage, high current DC-DC converters.
