UC3844BD1013TR Overview


With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. PMIC is packaged in a solid enclosure of Tape & Reel (TR). It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control has a supply voltage and operating voltage of 10V~30V. Workable in an dc switcher where 0°C~70°C TJ is the 0°C~70°C TJrm. Switching can be done at Up to 500kHz with this switching controller. The Surface Mount makes it ideal for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 8 terminations. 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 15V. Other relevant dc to dc converter ics will be returned if you search "UC3844". The switching converter has a total of 8 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. Statistically, DC regulator outputs 5V volts. You should note that the dc dc regulator's usual output current is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at a frequency of 500kHz. In a dormant state, the dc switching uses 12mA. Input voltage can be set to 15V for nominal working status. In the presence of a current greater than 17mA, the component may fail to operate properly and may be damaged.
