SG3844G BiCMOS Green-Mode PWM Controllers

Product Specification BiCMOS Green-Mode PWM Controllers SG3842G/ 3843G/ 3844G/ 3845G start-up current has been reduced to 5uA, and the minimum operating current has been reduced to 5mA. Each SG384xG has a slew rate controlled high current totem pole output, ideally suited for driving a power MOSFET while keeping EMI low. The current-sense propagation delay is typically 50ns, resulting in significantly more effective constant power protection. During normal operation, a SG384xG controller acts a.
