4-Channel TFT-LCD Supply  
Features  
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  
• 4.5V to 13V input  
• Boost controller for A  
VDD  
• Regulated LDOs for V  
and V  
ON  
achieve the required A  
output voltage. Both V  
and  
are generated using off-chip charge-pumps which are  
OFF  
• Buck controller for logic output  
• V slicing circuit  
VDD  
ON  
V
OFF  
then post regulated using on-board LDO controllers.  
ON  
The logic supply is generated using an internal non-  
synchronous buck controller. This controller runs at 180° out  
• Fully fault-protected  
of phase with the A  
VDD  
supply to minimize input noise.  
• Programmable sequence  
• 1MHz switching frequency  
• 38 Ld QFN package  
The A  
, V  
, and V  
outputs are automatically  
, and V . By using an optional  
VDD OFF ON  
sequenced as A  
, V  
VDD OFF ON  
external series transistor with A  
(Q1), the start-up  
VDD  
sequence can be adjusted to VOFF, A  
• Pb-free plus anneal available (RoHS compliant)  
and then V . A  
ON  
VDD  
slicing circuit is also included to reduce LCD flicker.

Applications  
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  
external transistor is required).  
• LCD-TVs (up to 50”+)  
• LCD monitors (15”+)

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.
