PRELIMINARY* ISL8601 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. Pinout ISL8601 (40 LD 6x6 QFN) Features • Input Voltage Range: +1.8V to 13.2V • VBIAS Voltage Range: +4.5V to 13.2V • Minimum Output Voltage: +0.5V • ±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 • Integrated 2A to 4A MOSFET Drivers • External Frequency Synchronization • Selectable Phase Delay: 0°, 90°, 120°, 180°, 240°, or 270° • Precision MOSFET rDS(ON) or Inductor DCR Current Sensing • Voltage Feedforward Compensation • Extensive PMBus Compliance • Broad PMBus Programmability Including Output Voltage, Overvoltage Threshold, Overcurrent Threshold, Overtemperature Threshold, Switching Frequency, Turn- On and Turn-Off • PMBus Monitoring of Load Current, Input Voltage, Output Voltage and Temperature • PMBus Programming Via I2C Interface • Resistor Programming of Select PMBus Parameters • Operating Frequency Range: 200kHz to 2MHz • Internal and External Temperature Measurement • Overvoltage, Undervoltage and Overtemperature Protection • Low-Side and High-Side Overcurrent Protection • Programmable Supply Sequencing and Tracking • Digital Soft-Start with Multiple Soft-Start Modes • Multiple Programmable Fault-Handling Modes • Multiple Prebiased Startup Options • Differential Remote Voltage Sensing • Power-Good Output with Programmable Delay Applications • Ethernet Routers and Switches • Point-of-Load Modules • Industrial Power Management Ordering Information PART NUMBER TEMP RANGE (°C) PACKAGE PKG.
