Description

The UCx84xA family of control devices is a pin-for-pin compatible improved version of theUCx84x family. Providing the necessary features to control current-mode or switched-mode powersupplies, this family of devices has many improved features: startup current is less than 0.5 mA,oscillator discharge is trimmed to 8.3 mA, and during UVLO, the output stage can sink at least 10mA at less than 1.2 V for VCC over 5V.

Feature

  • Optimized for Off-Line and DC-DC Converters
  • Low Start-UpCurrent (< 0.5 mA)
  • Trimmed Oscillator DischargeCurrent
  • Automatic Feedforward Compensation
  • Pulse-by-PulseCurrent Limiting
  • Enhanced Load ResponseCharacteristics
  • Undervoltage Lockout With Hysteresis
  • DoublePulse Suppression
  • High-Current Totem PoleOutput
  • Internally-Trimmed Bandgap Reference
  • Up to 500-kHzOperation
  • Create a Custom Design Using the UCx84xA With theWEBENCH? Power Designer
