LTC1649IS#PBF Overview


In the 16-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. It is sufficient to generate 1 outputs with this dc motor controller. There is a Tube solid enclosure around the pmic. The program can handle Transistor Driver dc switching's outputs (s). A 2.7V~5V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with -40°C~85°C TA. Switching can be done at 200kHz with this switching controller. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . An array of 16 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 3.3V. LTC1649 can be used to locate other relevant dc to dc converter ics. There are only 16 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended that the input voltage of the dc dc voltage regulator be 2.7V. Test statistics indicate DC regulator outputs 2.5V voltage. The dc to dc regulator can only accept a maximum input voltage of 5V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 20A. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. It is estimated that this dc regulatorhas a maximum frequency of 325kHz.
