MAX1889 General Description

General DescriptionThe MAX1889 provides the three regulated output voltages required for active matrix, thin-film transistor liquid crystal displays (TFT LCDs). It combines a high-performance step-up regulator with two linear-regulator controllers and multiple levels of protection circuitry for a complete power-supply systemFeatures♦ High-Performance Step-Up Regulator Fast Transient Response Current-Mode Control Architecture Built-In High-Efficiency N-Channel Power MOSFET Current-Limit Comparator>85% Efficiency Selectable Switching Frequency (500kHz/1MHz)Internal Soft-Start♦ Positive Linear-Regulator Controller♦ Negative Linear-Regulator Controller♦ Triple-Level Protection Against Smoke or Fire Input Switch Replaces Input Fuse Output Overload Detection with Timer Latch Thermal Shutdown♦ 2.7V to 5.5V Input Operating Range♦ Ultra-Small External Components♦ 1µA Shutdown Current (max)♦ 1mA Quiescent Current (max)♦ Ultra-Thin 16-Pin QFN Package (0.8mm Maximum Thickness)
