SG3843G, SG3842G, 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
