Wide VIN, 7V To 25V, Single-Phase PWM Controller With Integrated MOSFET Drivers

The ISL8106 is a Single-Phase Synchronous-Buck PWM Controller with a input voltage range of +7.0V to +25.0V featuring Intersil's Robust Ripple Regulator (R3) technology that 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-continuousconduction- 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 30 for an overcurrent fault, 60 for an overvoltage fault, or 90 for either an undervoltage fault or during soft-start. Overcurrent protection is accomplished by measuring the voltage drop across the rDS(ON) of the bottom-side MOSFET A single resistor programs the overcurrent and short-circuit points. Overvoltage and undervoltage protection is monitored at the FB voltage feedback pin.
