Key Features
- Unregulated single-output DC-DC conversion with 15 V nominal input (13.5 V to 16.5 V range) to 12 V output for embedded power isolation
- Up to 10% load regulation with SMA (R-PSMA-P4) package for compact, board-mount isolated power in space-constrained designs
- RoHS-compliant and REACH-compliant construction for use in environmentally regulated industrial and commercial applications
Applications
The RI3-1512S is designed for isolated power conversion in embedded systems, industrial controllers, and instrumentation where a 15 V bus must be converted to a 12 V isolated output. It is suitable for powering sensor interfaces, gate drive circuits, and analog signal conditioning modules that require galvanic isolation from the main power rail. The SMA package simplifies board integration in space-constrained PCB designs.

Frequently Asked Questions
What is the input voltage range of the RI3-1512S, and how does its unregulated topology affect output voltage accuracy?
The RI3-1512S accepts an input voltage range of 13.5 V to 16.5 V with a 15 V nominal. As an unregulated DC-DC module, the 12 V output voltage varies proportionally with input voltage changes and load current, with a maximum load regulation of 10%. This means the output can deviate up to 10% from nominal under full-load versus no-load conditions, which should be accounted for in downstream circuit design.
In which industrial or embedded applications is the RECOM RI3-1512S most appropriate for isolated 12 V power?
The RI3-1512S is well-suited for applications requiring isolated 12 V power from a 15 V rail, such as gate driver power supplies for MOSFETs or IGBTs, isolated analog measurement circuits, and RS-485 or CAN bus transceiver power in industrial control systems. Its single-output design and compact SMA package make it a practical choice for point-of-load isolated power in embedded PCBs.
How does the SMA package of the RI3-1512S compare to DIP packages for PCB integration, and what is its JESD-30 code?
The RI3-1512S uses the SMA package designated by JESD-30 code R-PSMA-P4, which is a surface-mountable 4-pin package offering a smaller footprint than traditional DIP-4 isolated DC-DC modules. This enables reflow soldering in automated assembly lines and allows closer component placement, reducing PCB area dedicated to isolated power conversion by a significant margin compared to through-hole alternatives.
