The UC2842A/3A/4A/5A family of control ICs is a pin-for-pin compatible improved version of the UC2842/3/4/5 family, providing the necessary features to control current-mode switched-mode power supplies.

Key Features:

Extended temperature performance of -40°C to 125°C, optimized for off-line and DC-to-DC converters.

Low start-up current (<0.5 mA) and trimmed oscillator discharge current.

Automatic feed-forward compensation, pulse-by-pulse current limiting, and enhanced load response characteristics.

Under-voltage lockout with hysteresis, double pulse suppression, and high current Totem Pole output.

Internally trimmed bandgap reference and 500 kHz operation with low Ro error amp.

Differences Between Family Members:

The main differences between the UC2842A, UC2843A, UC2844A, and UC2845A are the under-voltage lockout (UVLO) thresholds and maximum duty cycles.
