LTC1148HVCS#PBF Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. For 1 outputs, the dc motor controller is appropriate. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 3.5V~20V voltage are supplied and operated. 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 allows it to be used for dc dc regulator in general. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. 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. Some of the control techniques adapted by these dc dc converter ics include CONSTANT OFF TIME. It is inputted with a DC switcher's voltage of 10V. Other relevant dc to dc converter ics will be returned if you search "LTC1148". 14 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. A 1.25V voltage of DC regulator was detected in the test statistics. The dc dc regulator's usual output current is 50mA, which should be noted down when you start a project. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. Switching controller operates at a frequency of 250kHz. Since the dc switcher's maximum input voltage is 20V, the voltage must be regulated accordingly. The dc switcher will not provide an output current greater than 50mA. The controller should not be supplied with more current than 2.3mA.
