UC3879DW Product Details

UC3879DW Overview

In the 20-SOIC (0.295, 7.50mm Width) package, the switching controller meets most application requirements. 4 outputs can be generated with the dc motor controller. A solid enclosure of Tube surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 9V~20V. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at Up to 300kHz. A generalization of dc dc regulator can be made using Surface Mount. Frequency Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . The 20 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. Searching "UC3879" will return other relevant dc to dc converter ics. 20 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. A 2.2V voltage of DC regulator was detected in the test statistics. You should note that the dc dc regulator's usual output current is 10mA. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. A frequency of 300kHz is set for the switching controller. As a result, DC to DC voltage regulator has a value of ALSO HAS CONTROL MODE OF IPK, ALSO HAS CONTROL TECHNIQUE OF RESONANT so that the need can be met more directly. Input voltage can be set to 12V for nominal working status. It could be possible to satisfy the switching converter for operation with a current flow input of 23mA.
