Description
The UCx84xA family of control ICs is a pin-for-pin compatible improved version of the UCx84x family. Providing the necessary features to control currentmode or switched-mode power supplies, this family of devices has many improved features: startup current is less than 0.5 mA, oscillator discharge is trimmed to 8.3 mA, and during UVLO, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5 V.
