Data Sheet October 22, 2004 ISL6560 FN9011.3 Microprocessor CORE Voltage Regulator Two-Phase Buck PWM Controller The ISL6560 two-phase current mode, PWM control IC together with companion gate drivers, the HIP6601A, HIP6602A, HIP6603A or HIP6604 and MOSFETs provides a precision voltage regulation system for advanced microprocessors. Two-phase power conversion is a marked departure from earlier single phase 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 two phase converter operating at 350kHz per phase will have a ripple frequency of 700kHz. Higher converter bandwidth is also achievable, resulting in faster response to load transients. An outstanding feature of this controller IC includes highside current sensing with a single current sampling resistor in the input line to the output MOSFET transistors. This single current sampling resistor monitors each channels input current assuring excellent current sharing. Current mode control results in rapid response to changing load demands. Also featured are programmable VID codes with an accuracy of that range from and are set by the microprocessor. Pull up currents on these VID pins eliminates the need for external pull-up resistors. Another feature of this controller IC is the PWRGD monitor circuit and load protection circuits which provide overvoltage protection, overcurrent protection and undervoltage indication.
