Multi-phase Pwm Controller For Core-voltage Regulation

The ISL6557 provides core-voltage regulation by driving up to four interleaved synchronous-rectified buck-converter channels in parallel. Intersil multi-phase controllers together with Intersil MOSFET 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 4-phase operation, the ISL6557 offers the flexibility of selectable 2- or 3-phase operation. Simply connect the unused PWM pins to VCC. The channel switching frequency is adjustable in the range of 50kHz to 1.5MHz giving the designer the ultimate flexibility in managing the balance between high-speed response and good Thermal Management By Intersil Corporation
