ISL6269BIRZ規(guī)格書詳情
The ISL6269B 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.
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
signal VR, analogous to the output inductor ripple current. The
AC signal VR enters a window comparator where the lower
threshold is the error amplifier output VCOMP and the upper
threshold is a programmable voltage reference VW, resulting in
generation of the PWM signal. The voltage reference VW 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
ISL6269B has an error amplifier that provides ±1 voltage
regulation at the FB pin.
The ISL6269B 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 ISL6269B
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.
