LTC1142LCG-ADJ#PBF Product Details
LTC1142LCG-ADJ#PBF Overview
As a result of 28-SSOP (0.209, 5.30mm Width) compact design, the switching controller is compatible with most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 3.5V~18V. A 0°C~70°C TA dc switcher is not a problem. With this switching controller, you can switch at Up to 250kHz. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a DUAL terminal on the switching converters. 28 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including CONSTANT OFF TIME. The DC switcher's nominal voltage is 10V. Other relevant dc to dc converter ics can be found by searching "LTC1142". It is recommended that the input voltage of the dc dc voltage regulator be 3.5V. Current is output to the greatest value of 0.05A.
