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_MAXand 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
