Current Mode PWM Controller

The UC1842A 3A/4A/5A family of control ICs is a pin for pin compatible improved version of the UC3842 3/4/5 family. Providing the necessary features to control current mode switched mode power supplies, this family has the following improved features. Start up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA. During under voltage lockout, the output stage CAN sink at least 10mA at less than 1.2V for VCC over 5V.
