Pulsiv PSV-AD-250-Q24I | Demoboard PSV-AD-150
PULSIV OSMIUM MICRCONTROLLER FOR AC TO DC CONVERSION IN ALWAYS EFFICIENT POWER SUPPLIES (<250W)
Overview
| Topology | Other Topology |
| IC revision | 4 |
Description
The PSV-AD-xxx controller family has been designed to make power supplies more sustainable while reducing overall system cost. This scalable solution delivers efficient AC/DC conversion using smaller, lower cost, and more robust system components. Pulsiv’s unique switching architecture and intelligent control techniques have been combined to deliver consistent performance across the full load range and meet strict efficiency requirements at low power. When combined with supporting components, the PSV-AD-xxx can interface with any compatible DC/DC converter to produce ultra-compact power supplies. Please note that the default system components recommended in this document have been fully optimised for cost and customers have the freedom to replace any parts where size/performance takes priority.
Features
- Designed for high efficiency, low-cost, compact and lightweight AC/DC power supplies from 1-250W
- Universal Input AC85 – 264V
- High efficiency (99.5% peak) across the full load range
- Inrush current completely eliminated
- Compatible with any suitable DC/DC converter
- Meets EMC Class B
- Optional Active Bridge to further improve efficiency
- Suitable for a variety of high-volume consumer applications including Laptops, TV’s, Battery Chargers, LED Lighting and Industrial Power Supplies.
