TL2845BDR Product Details

TL2845BDR Overview


With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 1. There is a Tape & Reel (TR) solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Qualified to work in an dc switcher with -40°C~85°C TA. The switching controller can be switched at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of dc switching's functions can be performed on 14 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Searching "TL2845" will return other relevant dc to dc converter ics. 14 pins are present on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. As determined by the test statistics, the output voltage of DC regulator is 30V. You should note that the dc dc regulator's usual output current is 200mA. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. Switching controllers work at 500kHz Hz. For nominal working status, the input voltage can be set as 5.5V. Switching controller is necessary to supply a voltage of 15V. In order to ensure proper operation, the controller should not receive more current than 30mA.
