MAX8716 Dual Power-Supply Controller

MAX8716 Description

19-3569; Rev 2; 4/07 EVAALVUAAILTAIOBNLEKIT Interleaved High-Efficiency, Dual Power-Supply Controllers for Notebook Computers MAX8716/MAX8717/MAX8756.
The MAX8716/MAX8717/MAX8756/MAX8757 are dual, step-down, interleaved, fixed-frequency, switch-mode power-supply (SMPS) controllers with synchronous re.

MAX8716 Features

* o Fixed Switching Frequency 200kHz, 300kHz, or 500kHz 250kHz, 300kHz, or 400kHz (MAX8756 Only) o No Current-Sense Resistor Required o 40/60 Optimal Interleaving o Reduced Input-Capacitor Requirement o Output Voltage Fixed or Adjustable Outputs (Dual Mode™) 3.3V/5V Fixed or 1V to 5.5V Adjustable 1.5V

MAX8716 Applications

* compared to 180° out-of-phase regulators where the dutycycle overlap occurs when the input drops below 10V. Accurate output current limit is achieved using a sense resistor. Alternatively, power dissipation can be reduced using lossless inductor current sensing. Independent ON/OFF controls and powe
