LTC1148CN-3.3#PBF Overview


It comes in a 14-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. It is sufficient to generate 1 outputs with this dc motor controller. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). 3.5V~20V is the operating voltage and supply voltage of the dc control. Work well in dc switchers with a 0°C~70°C TA. A switching controller such as this can switch at a value of Up to 250kHz . A generalization of dc dc regulator can be made using Surface Mount. The dcdc regulator features Current Limit, Enable for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. 14 terminations with a variety of function. A few of the control techniques these dc dc converter ics adapt include CONSTANT OFF TIME. A DC switcher's nominal voltage of 10V is input. LTC1148 can be searched for other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. Statistically, DC regulator outputs 3.3V volts. The output value is set to the greatest value of 0.05A.
