The ISL78020 and ISL78022 integrate a high performance boost regulator with 2 LDO controllers for V_ON and V_OFF, a V_ON-slice circuit with adjustable delay and either one (ISL78020) or five (ISL78022) amplifiers for V_COM and V_GAMMA 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 V_ON, V_OFF, as well as providing start-up sequence control and fault protection.

The amplifiers are ideal for V_COM and V_GAMMA applications, with 150mA peak output current drive, 12MHz bandwidth, and 12V/μs slew rate. All inputs and outputs are rail-to-rail.

Available in a 32 Ld TQFP (7mmx7mm) Pb-free package, the ISL78020, ISL78022 are specified for operation over a -40°C to +105°C temperature range.
