Description
The SG3842GZS is a current-mode PWM controller designed for high performance and energy-saving capabilities. It is part of the SG348xG series, which offers improved features and functionality compared to previous models. The SG3842GZS is fully pin-compatible with bipolar UC384x devices and is compatible with the BiCMOS fabrication process for enhanced power conversion efficiency. With a minimal start-up current of 5uA and a minimum operating current of 5mA, this controller offers efficient power management. Additionally, it features a slew rate controlled high current totem pole output, ideal for driving a power MOSFET while keeping EMI low.
