SD4938-士兰微电子英文官网
WebSD4938 is a current mode PWM controller with 150V MOSFET used for SMPS. SD4938 integrates high-voltage start-up circuit. It enters burst mode at light load to reduce the system standby power dissipation; the frequency reduction function optimizes the conversion efficiency at light load; the soft startup function reduces the stress of device … WebMay 28, 2024 · This then raises the MOSFET drain from 12 volts to 15.9 volts (during flyback) and, given that your RCD snubber needs to overcome the forward drop of its own diode (maybe 0.7 volts), the peak voltage at the drain is 16.6 volts before any voltage is developed across the capacitor. reading war and peace
