Data Sheet

FN7493.2
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
A
VDD
generation, an integrated V
ON
charge pump, a V
OFF
charge pump driver, V
ON
slicing circuitry and a buck
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
A
VDD
-> V
OFF
-> V
ON
and A
VDD
/V
OFF
-> V
ON
sequences.
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掳C to +105掳C temperature range.
