LTC1148CS-5#PBF Overview


In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc controls with 3.5V~20V voltage are supplied and operated. Qualified to work in a 0°C~70°C TA dc switcher. Switching can be done at Up to 250kHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of 14 terminations are available in dc switching. These dc dc converter ics adapt a variety of control techniques, including CONSTANT OFF TIME. It is inputted with a DC switcher's voltage of 10V. Searching "LTC1148" will return other relevant dc to dc converter ics. In total, switching converter has 14 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4V. As determined by the test statistics, the output voltage of DC regulator is 5.05V. A maximum voltage of 20V is accepted by the dc to dc regulator as an input voltage. If you start a project, note down the dc dc regulator's usual output current of 50mA. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulator250kHz has the maximum frequency.
