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擄C to +105擄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.
