Overview of UC2843AQ

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.

Key Features

  • Extended Temperature Performance of –40°C to 125°C
  • Optimized for Off-line and DC to DC Converters
  • Low Start Up Current (<0.5 mA)
  • Trimmed Oscillator Discharge Current
  • Automatic Feed Forward Compensation
  • Pulse-by-Pulse Current Limiting
  • Enhanced Load Response Characteristics
  • Under-Voltage Lockout With Hysteresis
  • Double Pulse Suppression
  • High Current Totem Pole Output
  • Internally Trimmed Bandgap Reference
  • 500 kHz Operation
  • Low RO Error Amp
