The UC 1842A/3A/4A/5A family of control IC s is a pin for pin compatible improved version of the
UC 3842/3/4/5 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
0.5 mA. Oscillator discharge is trimmed to 8.3 mA. During under voltage lockout, the output stage can
sink at least 10 mA at less than 1.2 V for VCC over 5 V.
The difference between members of this family are shown in the table below.
