Overview
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 as a fixed frequency PWM controller.
The PWM frequency can be easily programmed by changing external RT and CT values.
The SG384xG includes two Green-mode functions that dramatically reduce power usage...
