19-0796; Rev 0; 4/07 EVALUATION KIT AVAILABLE Low-Cost, Dual-Output, Step-Down Controller with Fast Transient Response MAX8664 General Description Features The MAX8664 dual-output PWM controller is a low-cost, o ±0.8% Output Accuracy Over Load and Line high-performance solution for systems requiring dual o Operates from a Single 4.5V to 28V Supply power supplies. It provides two individual outputs thatoperate 180° out-of-phase to minimize input current o Simple Compensation for Any Type of Output ripple, and therefore, capacitance requirements. Built-in Capacitor drivers are capable of driving external MOSFETs to o Internal 6.5V Regulator for Gate Drive deliver up to 25A output current from each channel. o Integrated Boost Diodes The MAX8664 operates from a 4.5V to 28V input volt-age source and generates output voltages from 0.6V o Adjustable Output from 0.6V to 0.9 x VIN up to 90% of the input voltage on each channel. Total o Digital Soft-Start Reduces Inrush Current output regulation error is less than ±0.8% over load, o 100kHz to 1MHz Adjustable Switching line, and temperature. o 180° Out-of-Phase Operation Reduces Input The MAX8664 operates with a constant switching fre- Ripple Current quency adjustable from 100kHz to 1MHz. Built-in boostdiodes reduce external component count. Digital soft- o Overcurrent and Overvoltage Protection start eliminates input inrush current during startup. The o External Reference Input for Second Controller second output has an optional external REFIN2, facili- o Prebiased Startup Operation tating tracking supply applications. Each output iscapable of sourcing and sinking current, making the Ordering Information device a great solution for DDR applications. The MAX8664 employs Maxim s proprietary peak volt- PIN- PKG FAULT PART age-mode control architecture that provides superior PACKAGE CODE ACTION transient response during either load or line transients. MAX8664AEEP+ 20 QSOP E20-1 Independent This architecture is easily stabilized using two resistors
