Overview

19-2485; Rev 1; 10/02 MAX1889 Triple-Output TFT LCD Power Supply with Fault Protection General Description The 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 system.
The main DC-DC converter is a high-frequency (500kHz/1MHz), current-mode step-up regulator with an integrated N-channel power MOSFET that allows the use of ultra-small inductors and ceramic capacitors.
With its high closed-loop bandwidth performance, the MAX1889 provides fast tran...
