LTC1149CS-3.3#PBF Overview
As a result of 16-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at Up to 48V volts and has Up to 48V supply voltage. A 0°C~70°C TA dc switcher is not a problem. Switching can be done at Up to 250kHz with this switching controller. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable. An analog IC SWITCHING CONTROLLER is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 16 of dc switching. These dc dc converter ics adapt a variety of control techniques, including CONSTANT OFF TIME. You can find other relevant dc to dc converter ics by searching "LTC1149". In total, switching converter has 16 pins. The type is a particular Switching Regulator or Controllers of switching converter. DC regulator outputs 3.33V voltage according to the test statistics. The dc to dc regulator is limited to 48V input voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 50mA. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulator has a maximum frequency of 250kHz. The controller should not be supplied with more current than 3mA.
