The ISL78020 and ISL78022 integrate a high performance boost
regulator with 2 LDO controllers for VON and VOFF, a VON-slice circuit with adjustable delay and either one (ISL78020) or five (ISL78022) amplifiers for VCOM and VGAMMA applications.
The boost converter in the ISL78020 and ISL78022 is a current mode PWM type integrating an 18V N-Channel MOSFET. Operating at 1.2MHz, this boost converter can operate in either P-Mode for superior transient response, or in PI-Mode for tighter output regulation.
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.
