4-Channel TFT-LCD Supply
The ISL97522 represents a 4-channel supply control IC for
use in large panel TFT-LCD displays. Supporting inputs from
4.5V to 13V, the ISL97522 includes a boost controller to
achieve the required A VDD output voltage. Both V ON and
V OFF are generated using off-chip charge-pumps which are
then post regulated using on-board LDO controllers.
The logic supply is generated using an internal non-
synchronous buck controller. This controller runs at 180° out
of phase with the A VDD supply to minimize input noise.
The A VDD , V OFF , and V ON outputs are automatically
sequenced as A VDD , V OFF , and V ON . By using an optional
external series transistor with A VDD (Q1), the start-up
sequence can be adjusted to VOFF, A VDD and then V ON . A
V ON slicing circuit is also included to reduce LCD flicker.
The ISL97522 also incorporates a fault protection circuit that
can disable the IC and turn off all outputs when an output
short is detected. (Note that to protect A VDD a single
external transistor is required).

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.
