Beschreibung

AP3917B is an off-line universal AC Voltage input step-down regulator that provides accurate constant voltage (CV), outstanding low standby power, light loading efficiency and dynamics performance based on non-isolated buck topology. The main applications are for cost-effective home appliance power. Working with a single winding inductor and integrating a 650V MOSFET, the BOM cost is very low. The AP3917B EV1 Evaluation Board provides good design example for single output 12V@120mA power applications useful in home appliance powers.
