IC-Revision 1

Beschreibung

AP3917D 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. The chip supports non-isolated buck and buck-boost topology, and also isolated flyback topology. The main applications are for cost-effective home appliance power. Working with a single winding inductor and integrating a 700V MOSFET when used in buck topology, the BOM cost is very low. The AP3917D EV2 Evaluation Board contains two outputs specifications: 18V250mA and 5V50mA, with both non-isolations. The 18V250mA is buck topology and the other is flyback. The two topologies share a two-winding transformer. The feedback circuitry samples 18V output. The user’s guide provides good design example for dual output power applications in home appliance power.
