Single-Phase, PMBus-Enabled PWM

Features

Controller with Integrated FET Drivers

• Input Voltage Range: +1.8V to 13.2V

• VBIAS Voltage Range: +4.5V to 13.2V

• Minimum Output Voltage: +0.5V

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

• ±1.0% System Accuracy Over the Range of -40°C to

+85°C When Using the 0.8V Reference

• Internal Reference Voltage Programmable from 0.4V to

0.9V in 4mV Steps

ISL8601 supports both low-side MOSFET r

and

DS(ON)

• Integrated 2A to 4A MOSFET Drivers

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.

• External Frequency Synchronization

• Selectable Phase Delay: 0°, 90°, 120°, 180°, 240°, or 270°

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.
