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 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 ISL6219 also offers 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.
