Description

• Parameters: 150V CURRENT MODE PWM CONTROLLER
• Description: SD4938 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 to avoid transformer saturation.
