LTC1142CG#PBF Overview


As a result of 28-SSOP (0.209, 5.30mm Width) compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 2 outputs. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 3.5V~18V. Suitable for work in a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 250kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. There are many different types of terminations for 28. These dc dc converter ics adapt a variety of control techniques, including CONSTANT OFF TIME. DC switcher's voltage input is 10V. You can find other relevant dc to dc converter ics by searching "LTC1142". Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended to use 3.5V as the minimum input voltage of dc dc voltage regulator. Whenever the current value is 0.05A, switching converter outputs the highest possible value.
