TL3844BD Product Details

TL3844BD Overview


It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. The pmic is packaged in Tube solid enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. Voltages 10V~30V are the dc control's supply voltage and operating voltage, respectively. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. Using this switching controller, it is possible to switch at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at DUAL. 14 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. In addition to "TL3844", there are other relevant dc to dc converter ics you can find. There are 14 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 30V voltage according to the test statistics. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. Voltage regulator dc to dc is designed to operate at 48 % duty cycle during power-ups and power-downs to ensure reliability. There is 500kHz frequency setting on the switching controller. A nominal working status is achieved when the input voltage is set to 5.5V.
