The ISL78020 and ISL78022 integrate a high performance boost regulator with 2 LDO controllers for V_ONand V_OFF, a V_ON-slice circuit with adjustable delay and either one (ISL78020) or five (ISL78022) amplifiers for V_.COMand V_GAMMAapplications.Integration and V of ISL78020 and ISL78022_GammaThe application provides a high performance boost regulator_{of COM}2 LDO controllers and V_Vat_closeOne_VChip adjustable delay circuitry for either one (ISL78020) V or five (ISL78022) amplifiers.

The boost converter in the ISL78020 and ISL78022 is a current mode PWM type integrating an 18V N-Channel MOSFET.The ISL78020 and ISL78022 boost converters are current mode PWM types that incorporate 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.Operating at 1.2MHz, this boost converter can operate in P-mode with superior transient response, or in PI-mode with 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.When using an external low-cost transistor, the LDO controller provides a compact V_relateRegulation, five_close, as well as providing boot sequence control and fault protection.
