The ISL97642 integrates a high performance boost regulator with 2 LDO controllers for VON and VOFF, a VON-slice circuit with adjustable delay and three
amplifiers for VCOM and VGAMMA applications.
The boost converter in the ISL97642 is a current mode PWM type integrating an 18V N-Channel
MOSFET.
Using external low-cost transistors, the LDO controllers provide tight regulation for VON, VOFF, as well as providing start-up sequence control and fault protection.
