UC3856Q Overview


The switching controller fits in the 20-LCC (J-Lead) package and is ideal for most applications. This dc motor controller can be used to generate outputs with 2 numbers. PMIC is packaged in a solid enclosure of Tube. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 7V~40V and has a 7V~40V 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 200kHz . dc dc regulator is made easier with Surface Mount. To provide efficient switching control, Enable, Frequency Control, Soft Start is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at QUAD. Different dc switching's functions can be applied to 20 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC3856". Total pins of switching converter are 20. In particular, switching converter belongs to the Switching Regulator or Controllers family. The test statistics indicate that DC regulator outputs a voltage of 13.1V. 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. There is 1MHz frequency setting on the switching controller. 40V is the nominal working voltage.
