Description
General part information
5962-8670406 Series
The UC1843A-SP control IC is a radiation hardened pin-for-pin compatible 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 VCCover 5 V.
TheDevice Comparison Tableshows the difference between members of this family. Reference the individual product data sheets for ordering the radiation-improved version if available.
