description  
The UC2842A/3A/4A/5A family of control ICs is a pin for pin compatible improved version of the UC2842/3/4/5  
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 V  
5 V.
