RECOM DC-DC Converter, SIP4 Type, 3W Power Rating - RI3 Series - RI3-0509S

Struggling to cram components onto your circuit board? Use this compact DC-DC converter from RECOM to save space while boosting voltage to power-hungry devices. It takes in 5V DC and gives you a steady 9V DC in return, which you can use to power instrumentation and battery applications. As the unit delivers 3W power from a SIP4 package with dimensions of 11.5 (L) x 7.6 (W) x 10.2mm (H), you get high performance and a small footprint.

Features & Benefits

• Up to 90% efficiency to keep power waste and heat to a minimum

• Isolation voltage of 1kV separates the input and output, so you can be sure it's electrically safe

• Handles temperatures between -40°C and +85°C without derating for reliable operation in heavy plant environments

Applications

• Machine automation

• Process control

• Laboratory instruments

• Industrial computing

What's a SIP format?

A SIP format – or system-in-package – is where multiple integrated circuits are housed in a single electronic package. This one uses a single row of pins in an industry-standard format that's compatible with common electronics assembly systems. It lets you make board connections quickly and easily.
