High-Performance Notebook PWM
Controller
The ISL6269A IC is a Single-Phase Synchronous-Buck
PWM controller featuring Intersil's Robust Ripple Regulator
(R 3 ) 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.
Intersil’s R 3 technology combines the best features of fixed-
frequency PWM and hysteretic PWM while eliminating many
of their shortcomings. R 3 technology employs an innovative
modulator that synthesizes an AC ripple voltage signal V R ,
analogous to the output inductor ripple current. The AC
signal V R enters a window comparator where the lower
threshold is the error amplifier output V COMP , and the upper
threshold is a programmable voltage reference V W, resulting
in generation of the PWM signal. The voltage reference V W
sets 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.
The ISL6269A has 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 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.
