The ISL78010 is a multiple output regulator for use in all TFT-LCD automotive applications. It features a single boost converter with an integrated 2A FET, two positive LDOs for VON and VLOGIC generation, and a single negative LDO for VOFF generation. The boost converter can be programmed to operate in either P-mode for optimal transient response or PI-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 VOFF channels, the device is latched off until the input supply or EN is cycled. If a fault is detected on the VLOGIC channel, the device is latched off until the input supply is cycled. The VLOGIC channel is not affected by the EN function. The ISL78010 also includes an integrated start-up sequence for VLOGIC, VBOOST, VOFF, then VON or for VLOGIC, VOFF, VBOOST, and VON. The latter sequence requires a single external transistor. The timing of the start-up sequence is set using an external capacitor. The ISL78010 comes in a 32 Ld 5x5 TQFP package and is specified for operation over a -40°C to +105°C temperature range. It is AEC-Q100 rated.
