LTC1649CS Overview


With its 16-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 1 numbers. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) can be handled by it. 2.7V~5V is the operating voltage and supply voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. It can switch at 200kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. The dcdc regulator features Current Limit, Enable, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. DUAL are the position of the terminal of the switching converters. 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 PULSE WIDTH MODULATION. DC switcher's voltage input of 3.3V. In addition to "LTC1649", there are other relevant dc to dc converter ics you can find. In particular, switching converter belongs to the Switching Regulator or Controllers family. Input voltage of dc dc voltage regulator must be 2.7V. The dc to dc regulator can only accept 5V input voltage. Current is output to the greatest value of 20A.
