Description
LTC1149CS#PBF Overview
With its 16-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at Up to 48V and has a Up to 48V supply voltage. Worked in a 0°C~70°C TA dc switcher before. In this switching controller, the switch can be set to Up to 250kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 16 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include CONSTANT OFF TIME. Searching "LTC1149" will return other relevant dc to dc converter ics. 16 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Based on the test statistics, DC regulator outputs voltage 3.3V. If you are starting a new project, you should note the dc dc regulator's typical output current is 50mA. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. There is a maximum frequency of 250kHz on this dc regulators. In order to ensure the dc switcher's functionality, users must limit the voltage to 60V due to the dc switcher's maximum input voltage. In order to use a -15V voltage supply, switching controller is necessary to have one. DC switchers cannot produce output currents greater than 50mA. It is not recommended to supply more current to the controller than 3mA. Datasheets state the switching converter can output up to 5.2V volts. At least 4.9V voltage is output by the voltage controller.
