LTC1148HVCN#PBF Overview


With its 14-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 3.5V~20V. Worked in a 0°C~70°C TA dc switcher before. A switching controller such as this can switch at a value of Up to 250kHz . The Surface Mount allows it to be used for dc dc regulator in general. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. DUAL are the position of the terminal of the switching converters. The 14 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including CONSTANT OFF TIME. DC switcher's voltage input is 10V. Search for "LTC1148" to find other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4V. Statistically, DC regulator outputs 1.25V volts. 0.05A is the greatest value switching converter outputs as current. 2.3mA more than 2.3mA current should be supplied to the controller.
