ISL78010

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 V_ON and V_LOGIC 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 V_BOOST, V_ON or V_OFF channels, the device is latched off until the input supply or EN is cycled. If a fault is detected on the V_LOGIC channel, the device is latched off until the input supply is cycled. The V_LOGIC channel is not affected by the EN function.

The ISL78010 also includes an integrated start-up sequence for V_LOGIC, V_BOOST, V_OFF, then V_ON or for V_LOGIC, V_OFF, V_BOOST, and V_ON. 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 to +105 temperature range.
