LTC1143LCS Overview


Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. Packaging for the pmic consists of Tube solid enclosures. With Transistor Driver dc switching's output (s), it is able to handle it. The supply and operating voltage of the dc control are 3.5V~16V. Qualified to work in an dc switcher with 0°C~70°C TA. Using this switching controller, it is possible to switch at Up to 400kHz. dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Current Limit, Enable which allows efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. 16 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including CONSTANT OFF TIME. DC switcher's input voltageis set to 10V. LTC1143 can be searched for other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 3.5V.
