Interleaved High-Efficiency, Dual Power-SupplyControllers for Notebook Computers
The MAX8716/MAX8717/MAX8757 are dual, step-down, interleaved, fixed-frequency, switch-modepower-supply (SMPS) controllers with synchronous rec-tification. They are intended for main (5V/3.3V) and I/Opower generation in battery-powered systems.Fixed-frequency operation with optimal interleavingminimizes input ripple current from the lowest input volt-ages up to the 26V maximum input. Optimal 40/60 inter-leaving allows the input voltage to go down to 8.3Vbefore duty-cycle overlap occurs, compared to 180°out-of-phase regulators where the duty-cycle overlapoccurs when the input drops below 10V.Accurate output current limit is achieved using a senseresistor. Alternatively, power dissipation can bereduced using lossless inductor current sensing.Independent ON/OFF controls and power-good signalsallow flexible power sequencing. Soft-start reducesinrush current, while soft-stop gradually ramps the out-put voltage down preventing negative voltage dips. A low-noise mode maintains high light-load efficiencywhile keeping the switching frequency out of the audi-ble range.The MAX8716 is available in a 24-pin thin QFN pack-age, and the MAX8717/MAX8757 are available in a 28-pin thin QFN package
