TL2845BD Overview
It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. The dc motor controller is adquate to generate for 1 outputs. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). 7.6V~30V is the operating voltage and supply voltage of the dc control. Work well in dc switchers with a -40°C~85°C TA. Switching can be done at Up to 500kHz with this switching controller. dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. Different dc switching's functions can be applied to 14 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. TL2845 can be searched for other relevant dc to dc converter ics. Total pins of switching converter are 14. Switching converter type is specifically Switching Regulator or Controllers. A 30V voltage of DC regulator was detected in the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. Voltage regulator dc to dc is designed to operate at 48 % duty cycle during power-ups and power-downs to ensure reliability. Switching controller operates at 500kHz Hz. You can set the input voltage to 5.5V for nominal working status. A supply voltage of 15V is required. You should not supply more current than 30mA to the controller.
