R1S8-1209

Product Overview

The Recom Power R1S8-1209 is an ECONOLINE R1S (1W) isolated module DC-DC converter for board-mount power distribution. It provides a single 9 V output at up to 111 mA from a 10.8 V to 13.2 V input, delivering 1 W of output power. The 1 kV input-to-output isolation supports separated input and output circuits in compact commercial information technology equipment. Surface-mount construction in an 8-SMD module package allows placement on dense PCB layouts, with a footprint of 0.50 in by 0.42 in and a height of 0.28 in. The converter operates from -40°C to 100°C and has 78% efficiency. The device includes an SCP feature.

Key Features

• Recom Power ECONOLINE R1S (1W) isolated module DC-DC converter with one output.
• 9 V output at up to 111 mA, with 1 W output power.
• Input voltage range of 10.8 V to 13.2 V.
• 1 kV isolation between input and output.
• SCP feature, 78% efficiency, and -40°C to 100°C operating temperature range.
• Surface-mount 8-SMD module package measuring 0.50 in L x 0.42 in W x 0.28 in H.

Applications

• Commercial information technology equipment needing an isolated 9 V board-level rail.
• Low-power subsystems that require 1 W conversion from a 10.8 V to 13.2 V supply.
• Compact surface-mount power sections using an 8-SMD module with 1 kV isolation.

Design & Procurement Notes

Design considerations should focus on the 1 W output power, the 111 mA maximum output current, and the 10.8 V to 13.2 V input window. The 78% efficiency value supports thermal planning in the 8-SMD surface-mount package, whose 12.8 mm by 10.7 mm by 7.0 mm dimensions affect clearance and pad layout. The 1 kV isolation rating supports input and output separation, and the SCP feature is part of the device feature set. The -40°C to 100°C operating range and ITE (Commercial) context indicate a commercial board-level application.
