UC3845DR2G Overview
The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). It is capable of handling Transistor Driver dc switching's outputs (s). A 7.6V~30V 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. This switching controller can switch at 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . Various 14 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. UC384* can be used to locate other relevant dc to dc converter ics. In particular, switching converter belongs to the Switching Regulator or Controllers family. The minimum input voltage of the dc dc voltage regulator should be 8.2V. The dc to dc regulator can only accept 25V input voltage. 1A is the greatest value switching converter outputs as current.
