描述 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 VCC over 5 V.
The difference between members of this family are shown in the table below.
特性 Features
• Extended Temperature Performance of –40°C to 125°C
• Optimized for Off-line and DC to DC Converters
• Low Start Up Current (O Error Amp
