The UC184xA-SP family of control ICs is a pin-for-pin compatible improved version of the UC184x family. Providing the necessary characteristics to control current-mode switched-mode power supplies, this device has improved features. Start-up current is specified to be less than 0.5 mA and oscillator discharge is trimmed to 8.3 mA. During UVLO, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5 V.

The Device Comparison Table shows the difference between members of this family. Reference the individual product data sheets for ordering the radiation-improved version if available.
