The ISL78010 is a mulTIple output regulator for use in allTFT-LCD automoTIve applicaTIons. It features a single boostconverter with an integrated 2A FET, two posiTIve LDOs forVON and VLOGIC generation, and a single negative LDO forVOFF generation. The boost converter can be programmedto operate in either P-mode for optimal transient response orPI-mode for improved load regulation.The ISL78010 includes fault protection for all four channels.Once a fault is detected on either the VBOOST, VON or VOFFchannels, the device is latched off until the input supply orEN is cycled. If a fault is detected on the VLOGIC channel,the device is latched off until the input supply is cycled. TheVLOGIC channel is not affected by the EN function.The ISL78010 also includes an integrated start-up sequencefor VLOGIC, VBOOST, VOFF, then VON or for VLOGIC, VOFF,VBOOST, and VON. The latter sequence requires a singleexternal transistor. The timing of the start-up sequence is setusing an external capacitor.The ISL78010 comes in a 32 Ld 5x5 TQFP package and isspecified for operation over a -40°C to +105°C temperature range.
