UC3841DWTR Overview


Capsuled in the 18-SOIC (0.295, 7.50mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 8V~32V voltage are supplied and operated. Suitable for work in a 0°C~70°C TA dc switcher. This switching controller can switch at 500kHz. dc dc regulator is made easier with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. switching converters terminal (s) are designed to be at DUAL. The 18 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 20V. This dc dc voltage regulator should be powered by a voltage of 8V. The dc to dc regulator can only accept a maximum input voltage of 30V. DC to DC voltage regulator has the value of CURRENT MODE OPERATION IS ALSO POSSIBLE to better satisfy the requirement. Current is output to the greatest value of 1A.
