Product Description
- The UC2844AD is a current-mode Pulse Width Modulation (PWM) Controller providing the necessary features to control current-mode switched mode power supplies. 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.
- Optimized for off-line and DC to DC converters
- Trimmed oscillator discharge current
- Automatic feed forward compensation
- Pulse-by-pulse current limiting
- Enhanced load response characteristics
- Under-voltage lockout with hysteresis
- Double pulse suppression
- High current totem pole output Internally trimmed bandgap reference
- Low RO Error amplifier
- Green product and no Sb/Br
