ROF-785.0-0.5SMD RECOM POWER

Efficiency up to 95%,Non isolated, INNOLINE Features Very low profile 4mm DC/DC-Converter Wide input range.(4.75V ~ 36V) Short circuit protection, Thermal shutdown Non standard outputs available as specials Low ripple and noise EMC Compliant See Innoline Application Notes for use as an inverter (alternative to LM79xx Linear) 0.5 AMP SMD Description Single Output The ROF-78xx-0.5SMD high efficiency switching regulators are ideally suited to replace SMD linear regulators. The effi- ciency of up to 95% means that very little energy is wasted as heat so full power operation over the full industrial am- bient temperature range of -40C to +85C is possible. Low ripple and noise figures and short circuit , overload and over-temperature protection round off the specifications of this versatile converter series.This ROF-78xx-0.5SMD is compliant to EN 55022 CISPR 22 Class B (Emissions) with a simple external filter, EN 61000-6-1 and EN 61000-6-2 Crit A (Radiated Susceptability), EN 61000-4-2 Crit B (Electrostatic Discharge 4kV).

The diode can either be fitted across the device if the source is low impe- dance or fitted in series with the output (recom- mended).
