ISL9443IRZ Overview


Capsuled in the 32-VFQFN Exposed Pad package, the switching controller suits most application needs. 3 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. The system can process Transistor Driver dc switching's outputs (s). dc controls with 4.5V~28V voltage are supplied and operated. Worked in an dc switcher with a -40°C~85°C TA rating. The switching controller can be switched at 600kHz~1.2MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . A variety of terminations with 32 of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. A search for "ISL9443" will reveal other relevant dc to dc converter ics. dc dc voltage regulators should have a minimum input voltage of 4.5V.
