Features
• Very compact design: (4.1” × 2.25” × 1.06”)
• High power density - 7 W / inch³
• Full output power (70 W) in sealed enclosure at 40°C ambient
• High efficiency: 84% (85 V_AC), 89% (230 V_AC)
• Low no-load consumption: 350 mW (115 V_AC), 500 mW (230 V_AC)
• Low value input capacitor: 74% DC_MAX and line feed forward allows 2 µF/W
• Power limited during overload: overload output current less than 5 A at 19 V
• Primary side soft-start: minimizes component stresses during start-up
• Low EMI due to frequency jittering: meets CISPR22B with output cap. earthed
• Line under voltage sense: no output glitches on power up or power down
• Line over voltage shutdown: extended line surge protection
• Hysteretic thermal shutdown: supply automatically recovers when fault is removed
• Low component count: simple circuit and design
• Single sided PC board: no plated through holes
• No surface mount components required
