LTC1439IGW#PBF Overview


Capsuled in the 36-BSOP (0.295, 7.50mm Width) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. There is a Tube solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 3.5V~30V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~85°C TA rating. Using this switching controller, it is possible to switch at Up to 400kHz. The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Power on Reset, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. switching converters terminal (s) are designed to be at DUAL. Various 36 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "LTC1439". There are 36 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. It is recommended that the input voltage of the dc dc voltage regulator be 3.5V. DC regulator outputs 9V voltage according to the test statistics. In most cases, the dc dc regulator's output current is 2A. This information should be noted when you begin working with the component. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. There is a maximum frequency of 138kHz on this dc regulators.
