LTC1148HVCS-5#TRPBF Product Details
LTC1148HVCS-5#TRPBF Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 3.5V~20V. Qualified to work in a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 250kHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable for efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 14 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes CONSTANT OFF TIME. 10V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "LTC1148". Switching converter is a type of Switching Regulator or Controllers in particular. The minimum input voltage of the dc dc voltage regulator should be 3.5V. According to the test statistics, DC regulator outputs 5V voltage. It should be fully noted that the dc to dc regulator only accepts 20V input voltage at most. Switching converter outputs current to the greatest value of 0.05A. Current supplied to the controller should not exceed 2.3mA.
