UC3867DWTR Overview


This switching controller fits most application requirements since it is packaged in a 16-SOIC (0.295, 7.50mm Width) package. For outputs of 2, this dc motor controller is suitable. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 7V~22V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. There is a switch at 50kHz~500kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. Soft Start provides dcdc regulator efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . 16 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include RESONANT CONTROL. 12V nominal DC switcher's voltage input. Other relevant dc to dc converter ics will be returned if you search "UC3867". Total pins of switching converter are 16. The type is a particular Switching Regulator or Controllers of switching converter. It is recommended that the dc dc voltage regulator's minimum input voltage be 8V. Statistically, DC regulator outputs 1.7V volts. You should note that the dc dc regulator's usual output current is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. A frequency of 450kHz is used by the switching controller. A supply voltage of 12V is required.
