SLUSDD4B April 2019 – December 2020 UC1843B-SP
The UC1843B-SP control IC is a radiation hardened pin-for-pin compatible version of the UC1843A-SP. 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.
