DESCRIPTION  
The UC1842A/3A/4A/5A family of control IC's is a pin for pin compatible improved version of the UC1842/3/4/5  
family.Providing the necessary features to control current-mode switched-mode power supplies, this device 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 undervoltage 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 Table 1.
