UC3856DW Product Details

UC3856DW Overview


With its 16-SOIC (0.295, 7.50mm Width) package, the switching controller fits the needs of most applications. There is sufficient capacity to generate switching controller for outputs 2. The pmic is packaged in Tube solid enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. 7V~40V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a 0°C~70°C TA rating. There is a switch at 200kHz that can be used with this controller. dc dc regulator can be generalized using Surface Mount. Enable, Frequency Control, Soft Start is used for efficient switching control in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. A variety of 16 terminations are available in dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics will be returned if you search "UC3856". Pins number 16 of switching converter in total. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, DC regulator outputs 13.1V volts. In most cases, the dc dc regulator's output current is 500mA. This information should be noted when you begin working with the component. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. A frequency of 1MHz is used by the switching controller. Input voltage can be set to 40V for nominal working status. There is a requirement for a 15V supply voltage.
