General Description

The MAX1530/MAX1531 multiple-output power-supply controllers generate all the supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) monitors.

Both devices include a high-efficiency, fixed-frequency, step-down regulator.

The low-cost, all N-channel, synchronous topology enables operation with efficiency as high as 93%.
