Data Sheet
November 29, 2012
FN6325.2
3.3V to 20V, Single-Phase PWM Controller
with Integrated 2A/4A MOSFET Drivers
The ISL8118 is a single-phase PWM controller featuring an
input voltage range of +3.3V to +20V and integrated MOSFET
drivers. Utilizing voltage-mode operation with input voltage
feed-forward compensation, the ISL8118 maintains a constant
loop gain, providing optimal transient response for applications
with a wide input operating voltage range.
The output voltage can be precisely regulated down to 0.591V
with a system tolerance of ±1.0% over the induct rail
temperature range and line and load variations. A external
reference input is provided to bypass the internal reference for
voltage tracking or DDR memory applications. The compact
28 Ld 5x5 QFN package, integrated linear regulator as well as
the external linear regulator drive option, integrated differential
remote sense amplifier and integrated voltage margining with
adjustable upper and lower settings decrease external
component count and reduce board space requirements.
Programmable soft-start with pre-biased load capability,
adjustable operating frequency from 250kHz to 2MHz,
sourcing and sinking overcurrent protection, overvoltage and
undervoltage protection, and power-good indication with
programmable delay combine to make the ISL8118 a superior
choice for many power supply systems.

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 classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
