Diodes Incorporated AP3917D | Demoboard AP3917D EV2
Dual Output Off-Line Buck + Fly-back Power Solution
Overview
| Topology | Buck Converter |
| Input voltage | 85-264 V |
| Output 1 | 18 V / 0.25 A |
| IC revision | 1 |
Description
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.
