LTC1148HVCS-3.3#TRPBF Product Details
LTC1148HVCS-3.3#TRPBF Overview
It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 3.5V~20V. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at Up to 250kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 14 terminations. Some of the control techniques adapted by these dc dc converter ics include CONSTANT OFF TIME. DC switcher's voltage input of 10V. LTC1148 can be searched for 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. Statistically, DC regulator outputs 3.3V volts. This dc to dc regulator accepts only 20V input voltage at most. 0.05A is the greatest value switching converter outputs as current. A controller's current should not exceed 2.3mA.
