LTC1148CS#TRPBF Product Details
LTC1148CS#TRPBF Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. PMIC packaging is solid with a Tape & Reel (TR) enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 3.5V~20V. Work well in dc switchers with a 0°C~70°C TA. In this switching controller, the switch can be set to Up to 250kHz. dc dc regulator is made easier with Surface Mount. Current Limit, Enable provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminal (s) are designed at DUAL . 14 terminations with various dc switching's functions. CONSTANT OFF TIME is an example of one of the control techniques these dc dc converter ics adapt. 10V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC1148". Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 3.5V. A 1.25V voltage of DC regulator was detected in the test statistics. It should be fully noted that the dc to dc regulator only accepts 20V input voltage at most. Whenever the current value is 0.05A, switching converter outputs the highest possible value.
