ISL78010
FN6501.0
Automotive Grade TFT-LCD Power Supply
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
V_OFF 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°C to +105°C temperature
range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
