ISL6219 Datasheet Microprocessor Core Voltage Regulator

Manufacturer: Intersil (now Renesas)

Overview: ® ISL6219 Data Sheet June 2002 FN9080.1 Microprocessor CORE Voltage Regulator Precision Multi-Phase BUCK PWM Controller for Mobile Applications The ISL6219 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 buckconverter 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. Preconfigured for 3-phase operation, the ISL6219 also offers 2phase 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.

Key Features

  • on the ISL6219 include Dynamic-VID™ technology allowing seamless on-the-fly VID changes with no need for any additional external components. When the ISL6219 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 ISL6219 uses cost and space-saving rDS(ON) sensing for channel current balance and dynamic voltage positioning. Channe.
