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 r

DS(ON)

and

Inductor DCR current sensing. Programmable temperature

compensation for sensed current values is provided to ensure

maximum accuracy. In addition to the I

C 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.
