DATASHEET  
ISL6269A  
High-Performance Notebook PWM Controller  
FN9253  
Rev 3.00  
November 18, 2014  
The ISL6269A IC is a Single-phase Synchronous-Buck PWM  
controller featuring Intersil's Robust Ripple Regulator R3™  
Technology that delivers truly superior dynamic response to  
input voltage and output load transients. Integrated MOSFET  
drivers and bootstrap diode result in fewer components and  
smaller implementation area.  
Features  
• High performance R3™ Technology  
• Fast transient response  
• ±1% regulation accuracy: -10°C to +100°C and  
-40°C to +100°C  
Intersil’s R3™ Technology combines the best features of  
fixed-frequency PWM and hysteretic PWM while eliminating  
many of their shortcomings. R3™ Technology employs an  
innovative modulator that synthesizes an AC ripple voltage  
• Wide input voltage range: +5.0V to +25.0V  
• Output voltage range: +0.6V to +3.3V  
• Wide output load range: 0A to 25A  
signal V , analogous to the output inductor ripple current. The  
R
• Selectable diode emulation mode for increased light load  
efficiency  
AC signal V enters a window comparator where the lower  
R
threshold is the error amplifier output V  
, and the upper  
COMP  
• Programmable PWM frequency: 200kHz to 600kHz  
• Prebiased output start-up capability  
• Integrated MOSFET drivers and bootstrap diode  
• Internal digital soft-start  
threshold is a programmable voltage reference V resulting in  
generation of the PWM signal. The voltage reference V sets  
W
W,  
the steady-state PWM frequency. Both edges of the PWM can  
be modulated in response to input voltage transients and  
output load transients, much faster than conventional  
fixed-frequency PWM controllers. Unlike a conventional  
hysteretic converter, the ISL6269A has an error amplifier that  
provides ±1% voltage regulation at the FB pin.  
• Power good monitor  
• Fault protection  
- Undervoltage protection  
- Soft crowbar overvoltage protection  
The ISL6269A has a 1.5ms digital soft-start and can be  
started into a prebiased output voltage. A resistor divider is  
used to program the output voltage setpoint. The ISL6269A  
can be configured to operate in Continuous Conduction Mode  
(CCM) or Diode Emulation Mode (DEM), which improves  
light-load efficiency. In CCM the controller always operates as a  
synchronous rectifier, however when DEM is enabled, the  
low-side MOSFET is permitted to stay off, blocking negative  
current flow into the low-side MOSFET from the output  
inductor.  
- Low-side MOSFET r  
DS(ON)  
overcurrent protection  
- Over-temperature protection  
- Fault identification by PGOOD pull down resistance  
• Pb-free (RoHS compliant)  
Applications  
• PCI express graphical processing unit  
• Auxiliary power rail  
• VRM  
• Network adapter
