TL3845BD Overview


With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. There is sufficient capacity to generate switching controller for outputs 1. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Qualified to work in a 0°C~70°C TA dc switcher. A switching controller such as this can switch at a value of 100kHz . The Surface Mount allows it to be used for dc dc regulator in general. DCDC regulator is controlled efficiently by Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 14 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. 15V nominal DC switcher's voltage input. TL3845 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 14. Switching converter type is specifically Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 30V voltage. You should note down the dc dc regulator's usual output current of 200mA when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. Switching controllers work at 500kHz Hz. It is possible to set the input voltage to 5.5V for nominal working status. This voltage controller requires a supply voltage of 15V. It is important that the controller is supplied with 30mA more than 30mA volts of current.
