The UC3844AD8 is a current-mode Pulse Width Modulation (PWM) Controller providing the necessary features to control current-mode switched-mode power supplies. The start-up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA. During the under-voltage lockout, the output stage can sink at least 10mA at less than 1.2V for VCC over 5V.
Features:
- 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
Package Includes:
1 x UC3844AD8-TEXAS INSTRUMENTS-Current Mode PWM, 25V-12V supply, 500 kHz, 5V/200mA out, SOIC-8
