LTC1147LCS8#TRPBF Overview

Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. 3.5V~14V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with 0°C~70°C TA. The Surface Mount makes it ideal for general dc dc regulator. Current Limit, Enable provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a DUAL terminal on the switching converters. Various 8 terminations. CONSTANT OFF TIME is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 10V. A search for "LTC1147" will reveal other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 3.5V. The top frequency at which this switching controller can switch is 400kHz.
