UC3844AD8 - Current Mode PWM, 25V-12V Supply Soic8
Descrição geral do produto
The UC3844AD8 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
