Intersil's power solution for the mobile Pentium 4 processor comprises an ISL6215 multiphase PWM controller plus two or three ISL6205 MOSFET drivers for modular power partitioning. This architecture simplifies component placement, regulates channel current and offers more efficient heat distribution. The designer can configure the solution for two or three phases - three-phase providing higher efficiency, better heat management and a reduction in the number of high-cost filter capacitors. The ISL6215 controller offers many features optimised to power mobile processors eg, it automatically switches to single channel operation in low-power modes to reduce power and maximise efficiency. Voltage accuracy is maintained at 1% over entire temperature range. Each ISL6205 IC drives both the high and low side N-channel MOSFETs required in the synchronous-buck converter. Patented three-state PWM inputs significantly reduce negative transients on the output voltage, eliminating the need for an additional Schottky diode to protect from negative voltages. The ISL6205 handles phase voltages over a range of -5 to +25 V.
