Interleaved High-Efficiency, Dual Power-Supply

Controllers for Notebook Computers

General Description

Features

The MAX8716/MAX8717/MAX8757 are dual, step-

down, interleaved, fixed-frequency, switch-mode

power-supply (SMPS) controllers with synchronous rec-

tification. They are intended for main (5V/3.3V) and I/O

power generation in battery-powered systems.

♦ Fixed 200kHz, 300kHz, or 500kHz Switching

Frequency

♦ No Current-Sense Resistor Required

♦ 40/60 Optimal Interleaving

♦ Reduced Input-Capacitor Requirement

Fixed-frequency operation with optimal interleaving

minimizes input ripple current from the lowest input volt-

ages up to the 26V maximum input. Optimal 40/60 inter-

leaving 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 below 10V.

♦ 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

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 power-good signals

allow flexible power sequencing. Soft-start reduces

inrush current, while soft-stop gradually ramps the out-

put voltage down preventing negative voltage dips.

A low-noise mode maintains high light-load efficiency

while keeping the switching frequency out of the audi-

ble range.

♦ Soft-Start and Soft-Stop

♦ 2V Precision Reference with 0.75% Accuracy

♦ Independent Power-Good Outputs
