ISL6219A - Microprocessor CORE Voltage Regulator Precision Multi-Phase BUCK PWM Controller

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. Cha.

DATASHEET ISL6219A Microprocessor CORE Voltage Regulator Precision Multi-Phase BUCK PWM Controller for Mobile Applications FN9093 Rev.1.00 Mar 20, 2007 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.
