DH321 Datasheet - ON Semiconductor

DH321 Green Mode Power Switch

Each product in the FSDx321 (x for H, L) family consists of an integrated Pulse Width Modulator (PWM) and SENSEFET, and is specifically designed for high performance offline Switch Mode Power Supplies (SMPS) with minimal external components. Both devices are integrated high voltage power switching r.
