LTC1148LCS#TRPBF Product Details

LTC1148LCS#TRPBF Overview


In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs can be generated with the dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 3.5V~20V. Worked in an dc switcher with a 0°C~70°C TA rating. This switching controller can switch at Up to 250kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. Various 14 terminations. It includes CONSTANT OFF TIME as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 10V volts. Search for "LTC1148" to find other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. An input voltage of 3.5V is the minimum required for the dc dc voltage regulator. It should be noted that the dc to dc regulator only accepts 20V voltage as input voltage. Whenever the current value is 0.05A, switching converter outputs the highest possible value.
