Data Sheet
March 7, 2008
FN9257.2
8V to 14V, Single-Phase Synchronous
Buck Pulse-Width Modulation (PWM)
Controller With Integrated Gate Drivers
The ISL8104 is a 8V to 14V synchronous PWM controller
with integrated MOSFET drivers. The controller features the
ability to safely start-up into prebiased output loads and
provides protection against overcurrent fault events.
Overcurrent protection is implemented using top-side
MOSFET r DS(ON) sensing, eliminating the need for a current
sensing resistor.
The ISL8104 employs voltage-mode control with dual-edge
modulation to achieve fast transient response. The operating
frequency is adjustable from 50kHz to 1.5MHz with full (0%
to 100%) PWM duty cycle capability. The error amplifier
features a 15MHz (typ) gain-bandwidth product and 6V/μs
slew rate enabling high converter bandwidth.
The output voltage of the converter can be regulated to as
low as 0.597V with a tolerance of ±1.0% over the
commercial temperature range (0°C to +70°C), and ±1.5%
over industrial temperature range (-40°C to +85°C).
Provided in the QFN package, a SS pin and REFIN pin
enable supply sequencing and voltage tracking functionality.
