Description
The SG3842GAS is an electronic component model belonging to the IC Chips product category. It is a current-mode PWM controller that offers high performance and incorporates Green-mode power saving features. This controller is designed with improved features and functionality compared to the bipolar UC384x devices. The SG3842GAS is compatible with the BiCMOS fabrication process, allowing for low start-up and operating currents, thereby enhancing power conversion efficiency. It has a slew rate controlled high current totem pole output, ideal for driving power MOSFETs while minimizing electromagnetic interference (EMI).
