19-3569; Rev 2; 4/07 EVAALVUAAILTAIOBNLEKIT Interleaved High-Efficiency, Dual Power-Supply Controllers for Notebook Computers MAX8716/MAX8717/MAX8756/MAX8757 General Description The MAX8716/MAX8717/MAX8756/MAX8757 are dual, step-down, interleaved, fixed-frequency, switch-mode power-supply (SMPS) controllers with synchronous rectification. The MAX8716/MAX8717/MAX8756/MAX8757 are intended for main (5V/3.3V) power generation, while the MAX8756 is optimized for I/O power rails in batterypowered systems. Fixed-frequency operation with optimal interleaving minimizes input ripple current from the lowest input voltages up to the 26V maximum input. Optimal 40/60 interleaving allows the input voltage to go down to 8.3V before duty-cycle overlap occurs in 5V/3.
