TL3845DR Overview


It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. dc motor controller is suitable for 1 output generation. Cut Tape (CT) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for a 0°C~70°C TA dc switcher. It can switch at 100kHz. The Surface Mount allows it to be used for dc dc regulator in general. DCDC regulator is controlled efficiently by Frequency Control. Switch converters are connected to ICs with SWITCHING REGULATOR analog outputs. The switching converters's terminals (s) are designed at DUAL. A variety of terminations with 14 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "TL3845". There are a total of 14 pins 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 30V. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. 500kHz is the frequency of the switching controller. There are several dc to dc voltage regulator in the Automotive, AEC-Q100 series. DC switching uses 11mA when it is dormant. It is possible to set the input voltage as 5.5V for nominal working statuses. The supply voltage must be 15V. You should not supply more current than 30mA to the controller.
