ISL8840AMUZ Overview
As a result of 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). 9V~30V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a -55°C~125°C TJ rating. With this switching controller, you can switch at Up to 2MHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Current Limit, Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. Various 8 terminations. The control methods that these dc dc converter ics use include PULSE FREQUENCY MODULATION. DC switcher's input voltageis set to 15V. A search for "ISL8840A" will reveal other relevant dc to dc converter ics. The minimum input voltage of the dc dc voltage regulator should be 9V. It should be fully noted that the dc to dc regulator only accepts 30V input voltage at most.
