3 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 current-
mode 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.
