ISL9444IRZ Overview


With a 40-VFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 3 outputs. The pmic is packaged in Tube solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4.5V~28V and has a 4.5V~28V supply voltage. Worked in a -40°C~85°C TA dc switcher before. A switching controller such as this can switch at a value of 200kHz~1.2MHz . dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Phase Control, Power Fail, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. A variety of terminations with 40 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. Search for "ISL9444" to find other relevant dc to dc converter ics. The minimum input voltage of the dc dc voltage regulator should be 4.5V. This value is O/P VOLTAGE ADJUSTABLE FROM 0.7V so that DC to DC voltage regulator better serves the purpose.
