UC3851DWTR Product Details
UC3851DWTR Overview
This ac to dc converter is included in the package 18-SOIC (0.295, 7.50mm Width) .The AC/DC power converter type is Tape & Reel (TR) .There is a mounting point for this AC/DC converter in the way of Surface Mount .It is recommended that the ac dc converter be operated at a temperature of 0°C~70°C TA in order to ensure its performance.The AC DC converter uses a type SWITCHING CONTROLLER analog integrated circuit.When the switching frequency reaches Up to 500kHz , the circuit is closed.Within the range of 7.8V~32V supply voltage (Vcc/Vdd), it can be used.As a result, it has had 18 terminations.The ac/dc converter has a total of 18 pins.Up to 18 pins are present on the ac-dc converter.Search similar acdc converters based on UC3851 family members.There are 1 outputs to be processed.The ac to dc conversions are contained in Switching Regulator or Controllers .Current output is set to 400mA .This AC/DC converter produces a voltage of 40V as its output.This power AC DC is capable of reaching high efficiency when operating at a frequency of 450kHz .In the AC to DC transformer of a coverter, the output power generated is 1W .It is also possible to determine CURRENT MODE OPERATION IS ALSO POSSIBLE using this ACDC converter.
