The EL7585A represents a mulTIple output regulators for usein all large panel, TFT-LCD applicaTIons. It features a singleboost converter with integrated 3.5A FET, two posiTIve LDOsfor VON and VLOGIC generaTIon, and a single negative LDOfor VOFF generation. The boost converter can beprogrammed to operate in either P-mode or PI-mode forimproved load regulation.The EL7585A also integrates fault protection for all fourchannels. Once a fault is detected, the device is latched offuntil the input supply or EN is cycled. This device alsofeatures an integrated start-up sequence for VBOOST, VOFF,then VON or for VOFF, VBOOST, and VON sequencing. Thelatter requires a single external transistor. The timing of thestart-up sequence is set using an external capacitor. TheVLOGIC output is constantly enabled, but does shut downwhen a fault condition is detected.The EL7585A is specified for operation over the -40°C to+85°C temperature range.
