LTC1149CN#PBF Overview
This switching controller fits most application requirements since it is packaged in a 16-DIP (0.300, 7.62mm) package. The dc motor controller is adquate to generate for 1 outputs. Tube is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. Up to 48V is the supply voltage and the operating voltage of the dc control. Qualified to work in a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 250kHz. It is suitable for general dc dc regulator when it is set to Through Hole. DCDC regulator is controlled efficiently by Current Limit, Enable. An analog IC SWITCHING CONTROLLER is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. 16 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include CONSTANT OFF TIME. The DC switcher's nominal voltage is 12V. In addition to "LTC1149", there are other relevant dc to dc converter ics you can find. There are a total of 16 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 3.3V voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 50mA. DC switcher's Through Hole makes it qualified for most application and prototype designs. DC switcher'sThe switching controller works at a frequency of 250kHz. The dc switcher's maximum input voltage is 48V, so users must limit the voltage accordingly. Voltage 12V is needed for the supply. In order to ensure proper operation, the controller should not receive more current than 3mA. The switching converter could be operated with an input of 2.2mA current flow.
