LT1245CS8#PBF Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) can be handled by it. dc control's supply and operating voltages are 8.2V~25V. Worked in a 0°C~100°C TJ dc switcher before. dc dc regulator can be generalized using Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. Different dc switching's functions can be applied to 8 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "LT1245". 8 pins are present on switching converter. Switching converter is a special type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5V voltage. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. The duty cycle of the voltage regulator dc to dc can be set to 48 % on power-up or power-down to ensure reliability. 500kHz is the frequency of the switching controller. In a dormant state, the dc switching uses 170μA. 15V is the nominal working voltage. If the current exceeds 1A, the component may not operate correctly and may even be damaged.
