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.
