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 VAC), 89% (230 VAC)

•

Low no-load consumption: 350 mW (115 VAC), 500 mW (230 VAC)

•

Low value input capacitor: 74% DCMAX 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
