ISL8106
Wide VIN, 7V to 25V, Single-Phase PWM Controller with Integrated MOSFET Drivers
FN9283 Rev 1. 00 November 10, 2006
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 enab...
