Datasheet

RECOM DC-DC Converter, SIP-8 Package, 68% to 72% Efficiency - RSO Series - RSO-243.3S

Switch up your appliance's power supply with this DC-DC converter from RECOM. It dials input voltages down to a 3.3V DC output, taking the hassle out of adapting an electrical source to a machine. Don't worry about sending out unstable loads, as the unit's ±0.2% line regulation rating means it keeps its output steady for reliable power with each use. You can fix the device into a system in no time, thanks to its widely compatible through-hole mounting. The continuous short-circuit protection shuts this converter down if there's a fault, minimising the risk of electrical damage.

Features & Benefits

• Wide input voltage range between 18 and 36V for flexibility

• Low quiescent current of 25mA, minimising energy waste when switched off

• Resists surge voltages up to 1000V DC for consistency

• Maximum ripple voltage of 50mV to stop disruption from electrical noise

• Operates in temperatures ranging between -40°C and +85°C to withstand extreme conditions

Applications

• Domestic appliances

• Portable devices

• Manufacturing industry

How do I identify the pins on this converter?

For simple connection identification, the product's front side has a dot mark, helping you line up its contacts with the pinning diagram.
