The ISL8104 is a 8V to 14V synchronous PWM controller with integrated MOSFET drivers. The controller features the ability to safely start-up into prebiased output loads and provides protection against overcurrent fault events. Overcurrent protection is implemented using top-side MOSFET rsubDS(ON)/sub sensing, eliminating the need for a current sensing resistor.brbr The ISL8104 employs voltage-mode control with dual-edge modulation to achieve fast transient response. The operating frequency is adjustable from 50kHz to 1.5MHz with full (0% to 100%) PWM duty cycle capability. The error amplifier features a 15MHz (typ) gain-bandwidth product and 6V/µs slew rate enabling high converter bandwidth.brbr The output voltage of the converter can be regulated to as low as 0.597V with a tolerance of ±1.0% over the commercial temperature range (0°C to +70°C), and ±1.5% over industrial temperature range (-40°C to +85°C). Provided in the QFN package, a SS pin and REFIN pin enable supply sequencing and voltage tracking functionality.
