HAD SERIES - DUAL OUTPUT, 30 WATT
DESCRIPTION
FEATURES
HAD dual output DC/DC converters feature high • Independent Dual 5V and • Trim And Enable Pins
efficiency, open-frame packaging, and 1500 VDC
isolation. The HAD family allows board designers to
deliver any combination of power from either output, up
to each model’s maximum rating. The HAD uses planar
magnetics and has an MTBF of over a million hours.
3.3V Outputs
• Flexible Load Sharing
• High Efficiency Topology • Planar Magnetics
• Open-Frame Design
• Fixed Frequency
• 1500V Isolation
