LT3781IG Overview


Capsuled in the 20-SSOP (0.209, 5.30mm Width) package, the switching controller suits most application needs. It is sufficient to generate 1 outputs with this dc motor controller. Tube is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). Voltages 9V~18V are the dc control's supply voltage and operating voltage, respectively. Worked in a -40°C~85°C TA dc switcher before. Switching can be done at 700kHz with this switching controller. The Surface Mount makes it ideal for general dc dc regulator. To provide efficient switching control, Enable, Soft Start is included in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. A variety of terminations with 20 of dc switching. The nominal DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LT3781". Specially, switching converter corresponds to type Switching Regulator or Controllers. An input voltage of 9V is the minimum required for the dc dc voltage regulator.
