Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller
The HIP6303 multi-phase PWM control IC together with its companion gate drivers, the or HIP6603 and Intersil MOSFETs provides a precision voltage regulation system for advanced microprocessors. Multiphase power conversion is a marked departure from earlier single channel converter configurations previously employed to satisfy the ever increasing current demands of modern microprocessors. Multi-phase converters, by distributing the power and load current results in smaller and lower cost transistors with fewer input and output capacitors. These reductions accrue from the higher effective conversion frequency with higher frequency ripple current due to the phase interleaving process of this topology. For example, a three channel converter operating at 350kHz will have a ripple frequency of 1.05MHz. Moreover, greater converter bandwidth of this design results in faster response to load transients. Outstanding features of this controller IC include programmable VID codes from the microprocessor that range from to 2.05V with a system accuracy of ±1%. Pull up currents on these VID pins eliminates the need for external pull up resistors. In addition "droop" compensation, used to reduce the overshoot or undershoot of the CORE voltage, is easily programmed with a single resistor. Another feature of this controller IC is the PGOOD monitor circuit which is held low until the CORE voltage increases, during its Soft-Start sequence, to within 10% of the programmed voltage. Over-voltage, 15% above programmed CORE voltage, results in the converter shutting down and turning the lower MOSFETs ON to clamp and protect the microprocessor. Under voltage is also detected and results in PGOOD low if the CORE voltage falls 10% below the programmed level. Over-current protection reduces the regulator current to less than 25% of the programmed trip value. These features provide monitoring and protection for the microprocessor and power system.Features

Channel frequency, FSW, select and disable. A resistor from this pin to ground sets the switching frequency of the converter. Pulling this pin to ground disables the converter and three states the PWM outputs. See Figure 10.Bias and reference ground. All signals are referenced to this pin.
Power good monitor input. Connect to the microprocessorCORE voltage.
Voltage Identification inputs from microprocessor. These pins respond to TTL and 3.3V logic signals. The HIP6303 decodes VID bits to establish the output voltage. See Table 1.
PWM outputs for each driven channel in use. Connect these pins to the PWM input a HIP6601/2/3 driver. For systems which use 3 channels, connect PWM4 high. Two channel systems connect PWM3 and PWM4 high.
Enable pin normal operation is with input open or high. A low input disables the regulator and three states the PWM outputs.
Current sense inputs from the individual converter channel's phase nodes. Unused sense lines MUST be left open.
Output of the internal error amplifier. Connect this pin to the external feedback and compensation network.
Power good. This pin provides a logic-high signal when the microprocessor-CORE voltage (VSEN pin) is within specified limits and Soft-Start has timed out.
