ISL97661 pdf datasheet (4-Chan

The ISL97661 represents a high power, integrated LCD
supply IC targeted at large panel LCD displays. The
ISL97661 integrates a high power, 2.6A boost converter for
AVDD generation, an integrated VON charge pump, a VOFF
charge pump driver, VON slicing circuitry and a buck
regulator with 2A switch for logic generation.
The ISL97661 has been designed for ease of layout and low
BOM cost. Supply sequencing is integrated for both
AVDD -> VOFF -> VON and AVDD/VOFF -> VON sequences.
The TFT power sequence uses a separate enable to the
logic buck regulator for maximum flexibility.
Peak efficiencies are >90% for both the boost and buck while
operating from a 4V to 14V input supply. The current mode
buck offers superior line and load regulation. Available in the
36 Ld QFN package, the ISL97661 is specified for ambient
operation over the -40°C to +105°C temperature range.
