The UC1842A/3A/4A/5A family of control ICs is a pin for pin compati-
ble improved version of the UC3842/3/4/5 family. Providing the nec-
essary features to control current mode switched mode power
supplies, this family has the following improved features. Start up cur-
rent 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 1.2V for V
CC
over 5V.
The difference between members of this family are shown in the table
below.
