Open Frame Power Supplies and Medical Adapters

ActivePSR™ and ActiveQR™ platforms are well suited for industrial AC/DC open frame power supplies, power tool adapters and chargers, and medical adapters with strict performance requirements and size constraints. Our solutions exceed CE mark, Level V - ENERGY STAR 2.0, and US-CEC efficiency and standby requirements with comfortable margin, and deliver to power demands up to 60 Watts.

The ActivePSR™ flyback platform delivers best-in-class primary side regulated power adapters with the lowest bill of materials for applications delivering 12.5 Watts and less. Our secondary side regulated ActiveQR™ platform features optimized CCM and DCM advanced quasi-resonant operation, delivering up to 60 Watts.

Both ActivePSR™ and ActiveQR™ topologies are designed for state-of-the-art requirements for universal line regulation (85 to 265VAC), load regulation, ripple and voltage accuracy, fault protection, and EMI (e.g. CISPR/FCC Class B). Our fault protection profile includes over-voltage protection, brown out protection, over-temperature protection, short circuit protection, short winding protection, open loop protection, and more. All of our AC/DC converters feature jitter frequency modulation to reduce EMI.
