The UC2843AD is a current mode pulse width modulation (PWM) controller that provides the features
Product overview
The UC2843AD is a current mode pulse width modulation (PWM) controller that provides the necessary features to control current mode switched mode power supplies. The starting current is guaranteed to be less than 0.5 mA. Oscillator discharge is reduced to 8.3mA. During undervoltage lockout, the output stage can sink at least 10 mA to less than 1.2 V for VDC above 5 V.
Optimized for offline and DC to DC converters
Discharge current clipped oscillator
Automatic advance compensation
Pulse-by-pulse current limiting
Improved load response characteristics
Low voltage blocking with hysteresis
Double pulse suppression
