UC3843AN - TI Function Overview

The UC3843AN is a Current Mode PWM Controller optimized for off-line and DC to DC converters. Providing the necessary features to control current mode switched mode power supplies, this controller 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.
