UC2841N Product Details

UC2841N Overview

The switching controller fits in the 18-DIP (0.300, 7.62mm) package and is ideal for most applications. dc motor controller is suitable for 1 output generation. Tube is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 8V~32V voltage are supplied and operated. Work well in dc switchers with a -25°C~85°C TA. Using this switching controller, it is possible to switch at 500kHz. The Through Hole value makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start is included in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 18 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 20V volts. A search for "UC2841" will reveal other relevant dc to dc converter ics. There are a total of 18 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. A 40V voltage of DC regulator was detected in the test statistics. The dc dc regulator's usual output current is 400mA, which should be noted down when you start 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. The value of DC to DC voltage regulator is set to CURRENT MODE OPERATION IS ALSO POSSIBLE in order to better satisfy the requirement. It is possible to set the input voltage as 30V for nominal working statuses.
