INTERSIL ISL8106Manual
Update: 30 September, 2023
ISL8106 is a single-phase synchronous buck PWM controller from Intersil with an input voltage range of +7.0V to +25.0V. It features Intersil's Robust Ripple Regulator (R3) technology, which delivers exceptional dynamic response to input voltage and output load transients. Integrated MOSFET drivers, 5V LDO, and bootstrap diode result in fewer components and smaller implementation area for power supply systems. The ISL8106 features a 1.5ms digital soft-start and can be started into a pre-biased output voltage. A resistor divider is used to program the output voltage setpoint. The ISL8106 can be configured to operate in forced-continuous- conduction-mode (FCCM) or in diode-emulation-mode (DEM), which improves light-load efficiency. In FCCM the controller always operates as a synchronous rectifier, switching the bottom-side MOSFET regardless of the output load. With DEM enabled, the bottom-side MOSFET is disabled preventing negative current flow from the output inductor during low load operation. This makes the ISL8106 an excellent choice for all “green” applications. An audio filter prevents the PWM switching frequency from entering the audible spectrum due to extremely light load while in DEM. A PGOOD pin featuring a unique fault-identification capability significantly reduces system trouble-shooting time and effort. The pull-down resistance of the PGOOD pin is 30Ω for an overcurrent fault, 60Ω for OVP fault.
