MAX17030/MAX17036 19-4577 Rev 1 8/09 1/2/3-Phase Quick-PWM IMVP-6.5 VID Controllers General Description Features Triple/Dual-Phase Quick-PWM Controllers The MAX17030/MAX17036 are 3/2-phase interleaved Quick-PWM step-down VID power-supply controllers 2 Internal Drivers + 1 External Driver for IMVP-6.5 notebook CPUs. Two integrated drivers and 0.5% V Accuracy Over Line, Load, and OUT the option to drive a third phase using an external driver Temperature such as the MAX8791 allow for a flexible 3/2-phase con- 7-Bit IMVP-6.5 DAC figuration depending on the CPU being supported. Dynamic Phase Selection Optimizes Active/Sleep True out-of-phase operation reduces input ripple-current Efficiency requirements and output-voltage ripple while easing Transient Phase Overlap Reduces Output component selection and layout difficulties. The Quick- Capacitance PWM control provides instantaneous response to fast Transient Suppression Feature (MAX17036 Only) load-current steps. Active voltage positioning reduces power dissipation and bulk output capacitance require- Integrated Boost Switches ments and allows ideal positioning compensation for tan- Active Voltage Positioning with Adjustable Gain talum, polymer, or ceramic bulk output capacitors. Accurate Lossless Current Balance and The MAX17030/MAX17036 are intended for bucking Current Limit down the battery directly to create the core voltage. Remote Output and Ground Sense The single-stage conversion method allows this device Adjustable Output Slew-Rate Control to directly step down high-voltage batteries for the highest possible efficiency.

Note 2:SHDN might be forced to 12V for the purpose of debugging prototype breadboards using the no-fault test mode. Internal BST switches are disabled as well. Use external BST diodes when SHDN is forced to 12V. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
