Description

The UC1842A/3A/4A/5A family of conteol ICs is a pin for pin compatible improved version of the UC3842/3/4/5 family.Providing the necessary features to control current mode switched mode power supplies,this family has the following improved features.Start up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA.During under voltage lockout,the output stage can sink at least 10mA at less than 1.2Vfor vcc over 5V. The difference between members of this family are shown in the table below. UC2843AD8 Features &bull; Optimized for Off-line and DC to DCConverters&bull; Low Start UpCurrent(<0.5mA)&bull; Trimmend Oscillator Discharge Current&bull; High Current Totem Pole Output&bull; 500kHz Operation&bull; Low Ro Error Amp
