LT1243IS8#PBF Overview

Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. dc motor controller is suitable for 1 output generation. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 8.2V~25V voltage are supplied and operated. Worked in a -40°C~100°C TA dc switcher before. The Surface Mount allows it to be used for dc dc regulator in general. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 15V. LT1243 can be searched for other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 5V volts. The dc to dc regulator can only accept 25V input voltage. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. There is 500kHz frequency setting on the switching controller. The dc switching utilizes 170μA when it is in a dormant state.
