High-Efficiency, Quad-Output, Main PowerSupply Controllers for Notebook Computers
General Description
The MAX17003/MAX17004 are dual step-down, switchmode, power-supply (SMPS) controllers with synchronous rectification, intended for main 5V/3.
3V power generation in battery-powered 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, compared to 180° out-of-phase regulators where the duty-cycle overlap occurs when the input drops...
