Today’s high-performance microprocessors present many challenges to their power source. High power consumption,low bus voltages, and fast load changes are the principal characteristics which have led to the need for a switch-mode
DC-DC converter local to the microprocessor. Primarily created to serve this specific applications field, the Intersil HIP6006 and HIP6007 are voltage-mode controllers with many functions needed for implementing high-performance
voltage regulators. Figure 1 shows a simple block diagram of the HIP6006 and HIP6007. Each contains a highperformance error amplifier, a high-accuracy reference, a programmable free-running oscillator, and overcurrent protection circuitry. The HIP6006 has two MOSFET drivers for use in synchronous-rectified Buck converters.
