UC3844BDG Overview
As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. The program can handle Transistor Driver dc switching's outputs (s). 10V~36V is the operating voltage and supply voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Frequency Control is included in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. DUAL are the position of the terminal of the switching converters. 14 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Search for "UC384*B" to find other relevant dc to dc converter ics. The switching converter has a total of 14 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. This dc to dc regulator accepts only 25V input voltage at most. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. It is set to 48 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. A frequency of 52kHz is set for the switching controller. A current greater than 17mA may result in improper operation and possibly damage to the component.
