Description:
The MAX1513, MAX1514 provide complete power-supply solutions for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). Both devices include a high-performance step-up regulator controller, three linear-regulator controllers, and an adjustable delay block for startup sequencing. The MAX1513 includes an additional linear-regulator controller and a high-performance buffer amplifier. The devices can operate from 2.7V to 5.5V input supplies and provide overload protection with timer delay latch on all the regulated outputs.
