ISL97642 液晶 - 液晶显示的直流/直流集成放大器

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.

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.
