General Description
The MAX8716/MAX8717/MAX8757 are dual, step down, interleaved, fixed-frequency, switch-mode power-supply (SMPS) controllers with synchronous rectification. They are intended for main (5V/3.3V) and I/O power generation in battery-powered systems.

FEATUREs
♦ Fixed 200kHz, 300kHz, or 500kHz Switching Frequency
♦ No Current-Sense Resistor Required
♦ 40/60 Optimal Interleaving
♦ Reduced Input-Capacitor Requirement
♦ 3.3V and 5V fixed or 1.0V to 5.5V Adjustable Outputs (Dual Mode™)
♦ 4V to 26V Input Range
♦ Independently Selectable PWM, Skip, and Low Noise Mode Operation
♦ Soft-Start and Soft-Stop
♦ 2V Precision Reference with 0.75% Accuracy
♦ Independent Power-Good Outputs
