4-Channel Integrated LCD Supply

Features

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

• 4V to 5.5V input supply

• A boost up to 20V, with integrated 4.4A FET

VDD

• Integrated V

charge pump, up to 34V out

generation, an integrated V

charge pump, a V

slicing circuitry and a buck

charge pump driver, V

regulator with 2A switch for logic generation.

• V

charge pump driver, down to -18V

OFF

buck down to 1.2V, with integrated 2A FET

LOGIC

The ISL97651 have been designed for ease of layout and

low BOM cost. Supply sequencing is integrated for both

• Automatic start-up sequencing

- A -> V -> V or A

-> V

VDD OFF VDD OFF

-> V

and A

-> V

sequences.

- Independent logic enable

The TFT power sequence uses a separate enable to the

logic buck regulator for maximum flexibility.

• V slicing

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.

• Thermally enhanced thin QFN package (6mmx6mm)

• Pb-free plus anneal available (RoHS compliant)

Applications

• LCD monitors (15”+)

• LCD-TVs (40”+)

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.
