Product Details

The MAX17030/MAX17036 are 3/2-phase interleaved Quick-PWM™ 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 Quick-PWM 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.

A slew-rate controller allows controlled transitions between VID codes. A thermistor-based temperature sensor provides programmable thermal protection. An output current monitor provides an analog current output proportional to the sum of the inductor currents, which in steady state is the same as the current consumed by the CPU.
