Single-Phase, PMBus-Enabled PWM
Controller with Integrated FET Drivers
The ISL8601 is a single-phase PWM controller with integrated
MOSFET drivers utilizing analog voltage mode control. The
ISL8601 features extensive PMBus compliance that enables
rapid and flexible power supply design and comprehensive
product evaluation and testing. Exceptional flexibility in the
customization of operating parameters and system monitoring
functions is provided via the large PMBus command set. The
ISL8601 supports both low-side MOSFET rDS(ON) and
Inductor DCR current sensing. Programmable temperature
compensation for sensed current values is provided to ensure
maximum accuracy. In addition to the I2C interface, select
PMBus commands for the ISL8601 can also be programmed
via external resistors, bringing the power and flexibility of
PMBus into low-cost power supply systems.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are 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.
