The UC1843AMDREP is an enhanced current-mode Pulse Width Modulation (PWM) Controller 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.
