LTC1149CN-5#PBF Product Details
LTC1149CN-5#PBF Overview
The switching controller fits in the 16-DIP (0.300, 7.62mm) package and is ideal for most applications. dc motor controller is suitable for 1 output generation. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. A Up to 48V voltage is supplied to the dc control and used for operating it. Suitable for work in a 0°C~70°C TA dc switcher. With this switching controller, you can switch at Up to 250kHz. The Through Hole makes it ideal 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. There are a terminal (s) on the switching converters that are designed at DUAL. 16 terminations with various dc switching's functions. CONSTANT OFF TIME is an example of one of the control techniques these dc dc converter ics adapt. Other relevant dc to dc converter ics will be returned if you search "LTC1149". Total pins of switching converter are 16. Particularly, switching converter is a type of Switching Regulator or Controllers. A 5V voltage of DC regulator was detected in the test statistics. Considering the dc to dc regulator can only accept 48V input voltage, it is important to take note of this. There is a maximum frequency of 250kHz for this dc regulators. Whenever the current value is 0.05A, switching converter outputs the highest possible value. In order to ensure proper operation, the controller should not receive more current than 3mA.
