UC2851N Product Details
UC2851N Overview
It is embedded in package 18-DIP (0.300, 7.62mm) .Tube case is available for the ac dc converter.There is a AC/DC converter mounted in the way of Through Hole .The ac dc converter needs to be operated at -40°C~85°C TA °C in order to perform.SWITCHING CONTROLLER analog ICs are employed in this AC DC converter.When the switching frequency reaches Up to 500kHz , the process is complete.Supply voltage (Vcc/Vdd) does not need to exceed 7.8V~32V .It has a total of 18 terminations.On the ac/dc converter, there are 18 pins.There are 18 pins in total.Based on the UC2851 family, you can search for similar acdc converters.Running 1 outputs is available.Switching Regulator or Controllers includes the ac to dc conversions.400mA is set as the output current.There is 40V voltage output from it.AC to DC converter reaches high efficiency when operated at a frequency of 450kHz .There is 1W output power generated by a coverter.Also, CURRENT MODE OPERATION IS ALSO POSSIBLE can be found using this ACDC converter.
UC2851N Features
Packaged with 18-DIP (0.300, 7.62mm) Switching Frequency at Up to 500kHz With 18 pins Output Current at 400mA
