Description for the UC2842A

The UCx84xA family of control devices is a pin-for-pin compatible improved version of theUCx84x family. Providing the necessary features to control current-mode or switched-mode powersupplies, 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 10mA at less than 1.2 V for VCC over 5 V.
