4-Channel Integrated LCD Supply

The ISL97651 represents a high power, integrated LCD

supply IC targeted at large panel LCD displays. The

ISL97651 integrates a high power, 4.4A boost converter for

charge pump driver, V

regulator with 2A switch for logic generation.

The ISL97651 have been designed for ease of layout and

low BOM cost. Supply sequencing is integrated for both

The TFT power sequence uses a separate enable to the

logic buck regulator for maximum flexibility.

Peak efficiencies are 90% for boost and 92% for buck while

operating from a 4V to 5.5V input supply. The current mode

buck offers superior line and load regulation. Available in the

36 Ld QFN package, the ISL97651 is specified for ambient

operation over the -40°C to +105°C temperature range.

Ordering Information

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.
