LTC1148CS-3.3#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) are supported. dc control's supply and operating voltages are 3.5V~20V. A 0°C~70°C TA dc switcher is not a problem. It can switch at Up to 250kHz. The Surface Mount value makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable which allows efficient switching control. 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. Various 14 terminations. Some of the control techniques used by these dc dc converter ics are CONSTANT OFF TIME. A DC switcher's nominal voltage of 10V is input. Other relevant dc to dc converter ics will be returned if you search "LTC1148". Particularly, switching converter is a type of Switching Regulator or Controllers. An input voltage of 3.5V is the minimum required for the dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 3.3V. It should be noted that the dc to dc regulator only accepts 20V voltage as input voltage. The output of this function is the greatest value of 0.05A.
