Data Sheet

FN9283.1
Wide VIN, 7V to 25V, Single-Phase PWM
Controller with Integrated MOSFET
Drivers
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 (R 3 ) 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-continuous-
conduction-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 enabled, the bottom-side MOSFET is
disabled preventing negative current flow from the output
inductor during low load operation. This makes the ISL8106
an excellent choice for all “green” applications. An audio
filter prevents the PWM switching frequency from entering
the audible spectrum due to extremely light load while in
DEM.
A PGOOD pin featuring a unique fault-identification
capability significantly reduces system trouble-shooting time
and effort. The pull-down resistance of the PGOOD pin is
30 Ω for an overcurrent fault, 60 Ω for an overvoltage fault, or
90 Ω for either an undervoltage fault or during soft-start.
Overcurrent protection is accomplished by measuring the
voltage drop across the r DS(ON) of the bottom-side
MOSFET. A single resistor programs the overcurrent and
short-circuit points. Overvoltage and undervoltage protection
is monitored at the FB voltage feedback pin.
