Overview
MAX17003A/MAX17004A 19-0837; Rev 0; 6/07 EVAALVUAAILTAIOBNLEKIT High-Efficiency, Quad-Output, Main PowerSupply Controllers for Notebook Computers General Description The MAX17003A/MAX17004A are dual step-down, switch-mode, power-supply (SMPS) controllers with synchronous rectification, intended for main 5V/3.
3V power generation in battery-powered systems.
Fixedfrequency 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 dutycycle overlap occurs, compared to 180° out-of-phase regulators where the duty-cycle overlap occurs when the input drops below 10V.
Output current sensing provides peak current-limit protection, using either an accurate sense resistor or using lossless inductor DCR current sensing.
A low-noise mode maintains high light-load efficiency while keeping the switching frequency out of the audible range.
An internal, fi...
