Description

 The ISL6219A provides core-voltage regulation by driving up to three interleaved synchronous-rectified buck-converter channels in parallel. Intersil multi-phase controllers together with ISL6207 gate drivers form the basis for the most reliable power-supply solutions available to power the latest industry-leading microprocessors. Multi-phase buck-converter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents. Lower ripple results in lower total component cost, reduced dissipation, and smaller implementation area. Pre-configured for 3-phase operation, the ISL6219A offers the flexibility of 2-phase operation. Simply connect the unused PWM pin to +5V. The channel switching frequency is adjustable in the range of 100kHz to 1.5MHz giving the designer the ultimate flexibility in managing the balance between high-speed response and good thermal management. New features on the ISL6219A include Dynamic-VID™ technology allowing seamless on-the-fly VID changes with no need for any additional external components. When the ISL6219A receives a new VID code, it incrementally steps the output voltage to the new level. Dynamic VID™ changes are fast and reliable with no output voltage overshoot or undershoot. Like other Intersil multiphase controllers, the ISL6219A uses cost and space-saving rDS(ON) sensing for channel current balance and dynamic voltage positioning. Channel current balancing is automatic and accurate with the integrated current-balance control system. Overcurrent protection can be tailored to any application with no need of additional parts. An integrated DAC decodes the 5-bit logic signal present at VID0-VID4 and provides an accurate reference for precision voltage regulation. The high-bandwidth error amplifier and accurate voltage reference all work together to provide better than 0.8% total system accuracy, and to enable the fastest transient response available. A window comparator toggles PGOOD if the output voltage moves out of range and acts to protect the load in case of overvoltage.
