ISL97642IRTZ-TK

开关稳压器 TFT-LCD DC-DC W/ INTEGRTD AMP 1K

TFT-LCD DC/DC with Integrated Amplifiers

The ISL97642IRTZ-TK 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.
