LT1243CS8#PBF Overview
This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. The dc motor controller is adquate to generate for 1 outputs. A solid enclosure of Tube surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 8.2V~25V. Suitable for work in a 0°C~100°C TJ dc switcher. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . The 8 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. LT1243 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 8 pins. Switching converter type is specifically Switching Regulator or Controllers. DC regulator outputs 5V voltage according to the test statistics. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. It is set to 96 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. There is 500kHz frequency setting on the switching controller. The dc switching utilizes 170μA when it is in a dormant state. It is possible to set the input voltage as 15V for nominal working statuses.
