UC3841N Overview


It comes in the 18-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. For outputs of 1, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc controls with 8V~32V voltage are supplied and operated. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. There is a switch at 500kHz that can be used with this controller. As it has a Through Hole value, it can be used for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at DUAL . The 18 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. There is a DC switcher's nominal voltage of 20V. You can find other relevant dc to dc converter ics by searching "UC3841". In total, switching converter has 18 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 40V volts. normally, the dc dc regulator's output current is 400mA, which you should keep in mind when starting a project. The duty cycle of the voltage regulator dc to dc can be set to 95 % on power-up or power-down to ensure reliability. Switching controller operates at 450kHz Hz. For better satisfaction, the value of DC to DC voltage regulator is CURRENT MODE OPERATION IS ALSO POSSIBLE. Input voltage can be set to 30V for nominal working status. Input of 10mA current flow would satisfy the operation requirements of the switching converter .
