The UC1845A-SP control IC is a radiation hardened pin-for-pin compatible version of the UC184x family. It is primarily suited for Satellites and other harsh environment applications. 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.
