Introduction
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 can sink at least 10 mA at less than 1.2 V for VCC over 5 V.
Features
- 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
- Up to 500-kHz Operation
- Create a Custom Design Using the UCx84xA With the WEBENCH Power Designer
Applications
- Switch Mode Power Supplies (SMPS)
- DC-DC Converters
- Power Modules
- Industrial PSU
- Battery Operated PSU
