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 voltag...
