Overview

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.

Key Features

  • 4.5V to 13V input.
  • Boost controller for AVDD.
  • Regulated LDOs for VOFF and VON.
  • Buck controller for logic output.
  • VON slicing circuit.
  • Fully fault-protected.
  • Programmable sequence.
  • 1MHz switching frequency.
  • 38 Ld QFN package.
  • Pb-free plus anneal available (RoHS compliant).
