LT1243IS8#TRPBF Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. 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. Using this switching controller, it is possible to switch at 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. DUAL are the position of the terminal of the switching converters. A variety of dc switching's functions can be performed on 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. A DC switcher's nominal voltage of 15V is input. A search for "LT1243" will reveal other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. 8.2V should be the minimum input voltage for the dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 5V. Considering the dc to dc regulator can only accept 25V input voltage, it is important to take note of this. 1A is the largest value switching converter outputs.
