The MAX17030/MAX17036 are 3/2-phase interleaved Quick-PWMTM step-down VID power-supply controllers for IMVP-6.5 notebook CPUs. Two integrated drivers and the option to drive a third phase using an external driver such as the MAX8791 allow for a flexible 3/2-phase configuration depending on the CPU being supported. True out-of-phase operation reduces input ripple-current requirements and output-voltage ripple while easing component selection and layout difficulties. The QuickPWM control provides instantaneous response to fast load-current steps. Active voltage positioning reduces power dissipation and bulk output capacitance requirements and allows ideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors. The MAX17030/MAX17036 are intended for bucking down the battery directly to create the core voltage. The single-stage conversion method allows this device to directly step down high-voltage batteries for the highest possible efficiency.
