The UCx84xA family of control devices is a pin-for-pin compatible improved version of the UCx84x family. Providing the necessary features to control currentmode or switched-mode power supplies, 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 .
• Optimized for Off-Line and DC-DC Converters
• Low Start-Up Current (< 0.5 mA)
• Trimmed Oscillator Discharge Current
• Automatic Feedforward Compensation
• Pulse-by-Pulse Current Limiting
• Enhanced Load Response Characteristics
• Undervoltage Lockout With Hysteresis
• Double Pulse Suppression
• High-Current Totem Pole Output
• Internally-Trimmed Bandgap Reference
