description

The UC1842A/3A/4A/5A family of control ICs is a pin-for-pin compatible improved version of the UC3842/3/4/5family. Providing the necessary features to control current mode switched mode power supplies, this family hasthe following improved features. Start up current is guaranteed to be less than 0.5 mA. Oscillator discharge istrimmed to 8.3 mA. During under voltage lockout, the output stage can sink at least 10 mA at less than 1.2 Vfor VCC over 5 V.
The difference between members of this family are shown in the table below.
