LTC1148HVCN-3.3#PBF Overview
The switching controller fits in the 14-DIP (0.300, 7.62mm) package and is ideal for most applications. The dc motor controller is adquate to generate for 1 outputs. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). 3.5V~20V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a 0°C~70°C TA. Using this switching controller, it is possible to switch at Up to 250kHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 14 terminations. These dc dc converter ics adapt several control methods, including CONSTANT OFF TIME. There is a DC switcher's nominal voltage of 10V. LTC1148 can be used to locate other relevant dc to dc converter ics. Switching converter is a type of Switching Regulator or Controllers in particular. 4V should be the minimum input voltage for the dc dc voltage regulator. DC regulator outputs 3.3V voltage according to the test statistics. The output value is set to the greatest value of 0.05A. 2.3mA more than 2.3mA current should be supplied to the controller.
