LTC1649CS#TRPBF Product Details
LTC1649CS#TRPBF Overview
Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. For outputs of 1, this dc motor controller is suitable. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc control's supply and operating voltages are 2.7V~5V. A 0°C~70°C TA dc switcher is not a problem. A switching controller such as this can switch at a value of 200kHz . dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Soft Start which allows efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. 16 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 3.3V volts. LTC1649 can be searched for other relevant dc to dc converter ics. Input voltage of dc dc voltage regulator must be 2.7V. It should be noted that the dc to dc regulator only accepts 5V voltage as input voltage. A value of 20A is output as the maximum value of current.
