LT1243IN8#PBF Overview
As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. dc motor controller is suitable for 1 output generation. Tube is the solid enclosure in which PMIC is packaged. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 8.2V~25V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~100°C TA dc switcher. It is suitable for general dc dc regulator when it is set to Through Hole. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the DUAL position. The 8 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. A search for "LT1243" will reveal other relevant dc to dc converter ics. 8 pins are present on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. As determined by the test statistics, the output voltage of DC regulator is 12V. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. voltage regulator dc to dcs with a 96 % duty cycle are designed to be reliable when powered on and powered off. A frequency of 500kHz is used by the switching controller. This value is LG-MAX so that DC to DC voltage regulator better serves the purpose. During dormancy, the dc switching uses 170μA.
