The ISL6269 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, 5V LDO 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 ISL6269 has an error amplifier that provides ±1% voltage
regulation at the FB pin.
The ISL6269 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 ISL6269 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.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
