MAX1531 - Multiple-Output Power-Supply Controllers

Download the MAX1531 datasheet PDF. This datasheet also covers the MAX1530 variant, as both devices belong to the same multiple-output power-supply controllers family and are provided as variant models within a single manufacturer datasheet.

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.

www.DataSheet4U.com 19-2866; Rev 0; 5/03 Multiple-Output Power-Supply Controllers for LCD Monitors 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%. High-frequency operation allows the use of small inductors and capacitors, resulting in a compact solution. The MAX1530 includes three linear regulator controllers and the MAX1531 includes five linear regulator controllers for supplying logic and LCD bias voltages. A programmable startup sequence enables easy control of the regulators.
