TL3845D Product Details

TL3845D Overview


It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 7.6V~30V voltage are supplied and operated. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at 100kHz. A generalization of dc dc regulator can be made using Surface Mount. To provide efficient switching control, Frequency Control is included in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING REGULATOR output. Switching converters are designed with the terminal (s) at position DUAL . An array of 14 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "TL3845". 14 pins are on switching converter. Switching converter is a special type of Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 30V. You should note that the dc dc regulator's usual output current is 200mA. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controller operates at 500kHz Hz. The dc to dc voltage regulator belongs to the Automotive, AEC-Q100 series. A nominal working status is achieved when the input voltage is set to 5.5V. Voltage 15V must be supplied. In order to ensure proper operation, the controller should not receive more current than 30mA.
