RECOM has added a new range of SMD transformers for engineers building discrete isolated DC/DC supplies rather than using complete modules. The parts support flyback, push-pull, and full-bridge topologies from 1 W to 15 W, giving designers a more standard route into custom isolated power stages.
The range includes the RMR-xxx series for 1 W and 2 W push-pull or full-bridge designs, the RBE-xxx series for 6 W to 15 W flyback converters, and the RPE-021 and RPE-026 for higher-isolation and bidirectional battery applications. These transformers are designed to pair with RECOM’s own driver and controller ICs, including the RVP-xxx, RVPW-xxx, and RPSV013 families.
A Standard Option For Discrete Power Stages
The main idea here is straightforward. RECOM is offering standard SMD transformer options that cover common input and output combinations, so engineers do not have to start with a fully custom magnetic design for every isolated converter. Across the range, RECOM quotes isolation withstand voltages up to 5000 VAC for one minute. The parts are also rated for peak reflow temperatures up to 250°C for 10 seconds and can withstand two reflow cycles, which makes them easier to fit into standard SMT production flows.
Low-Power RMR Parts For Push-Pull And Full-Bridge Designs
The RMR-xxx series covers sub-miniature toroidal SMD transformers for 1 W and 2 W designs. These parts are intended for push-pull or full-bridge driver topologies, with isolation ratings from 1.5 kVDC to 4.5 kVDC for one minute. Two parts sit above that baseline. The RMR-028 and RMR-031 are higher-isolation versions with 5 kVAC and 7 kVDC withstand ratings, plus wider creepage and clearance distances. RECOM says these parts are designed to match its RVP-xxx transformer drivers.
RBE And RPE Parts Extend The Range
The RBE-xxx family covers 6 W to 15 W flyback designs using bobbin-type SMD transformers. RECOM lists isolation ratings from 1.5 kVDC to 6 kVDC for one minute, or 4.5 kVAC, and pairs the series with its RVPW-xxx flyback drivers.
The RPE-021 is another bobbin-type part with enhanced 6000 VDC isolation withstand and wider creepage and clearance. The RPE-026 is more application-specific, designed for bidirectional battery cell charging and discharging when used with RECOM’s RPSV013 bidirectional PWM controller and synchronous rectifier IC.
