† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
‡ Unless otherwise indicated, voltages are reference to ground and currents are positive into and negative out of the specified terminals.
NOTE 1: Long term hightemperature storage and/or extended use at maximum recommended operating conditions may result in a reduction ofoverall device life. See http://www.ti.com/ep_quality for additional information on enhanced plastic packaging.

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 VCC over 5 V.

The difference between members of this UC2842A/3A/4A/5A family are shown in the table below.
