LTC1149CN-3.3#PBF Overview
This switching controller fits most application requirements since it is packaged in a 16-DIP (0.300, 7.62mm) package. 1 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). Up to 48V is the operating voltage and supply voltage of the dc control. A 0°C~70°C TA dc switcher is not a problem. It can switch at Up to 250kHz. The Through Hole value makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (s) are designed at DUAL . 16 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include CONSTANT OFF TIME. Search for "LTC1149" to find other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 3.3V voltage. Considering the dc to dc regulator can only accept 48V input voltage, it is important to take note of this. Switching converter outputs current to the greatest value of 0.05A. It is important that the controller is supplied with 3mA more than 3mA volts of current.
