LT3781IG#PBF Overview


It comes in the 20-SSOP (0.209, 5.30mm Width) package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tube solid enclosure. The system can process Transistor Driver dc switching's outputs (s). This dc control operates at 9V~18V and has a 9V~18V supply voltage. Suitable for working in an dc switcher that has a -40°C~85°C TA. dc dc regulators can be carried out with Surface Mount. Enable, Soft Start provides dcdc regulator efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 20 terminations. DC switcher's voltage input is 12V. Other relevant dc to dc converter ics can be found by searching "LT3781". There are a total of 20 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. A 72V voltage of DC regulator was detected in the test statistics. You should note that the dc dc regulator's usual output current is 20A. DC regulator has a maximum frequency of 700kHz.
