ISL97642

Support is limited to customers who have already adopted these products.

The ISL97642 integrates a high performance boost regulator with 2 LDO controllers for V_ON and V_OFF, a V_ON-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 V_ON, V_OFF, as well as providing start-up sequence control and fault protection. The amplifiers are ideal for VCOM and VGAMMA applications, with 150mA peak output current drive, 12MHz bandwidth, and 12V/µs slew rate. All inputs and outputs are rail-to-rail. Available in the 32 Ld thin QFN (5mmx5mm) Pb-free package, the ISL97642 is specified for operation over the -40°C to +85°C temperature range.
