ISL97522 4-Channel TFT-LCD Supply RECOMMOEBNSDOELDEISTLRE9E8PP6RL0AO2CDEUMCETNT PART DATASHEET FN7445 Rev 0.00 December 13, 2006 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 achieve the required AVDD output voltage. Both VON and VOFF are generated using off-chip charge-pumps which are then post regulated using on-board LDO controllers. The logic supply is generated.
