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 V 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...
