Sixteenth brick DC/DC power modules deliver 25A

Lambda UK is strengthening its iSA series of sixteenth brick DC/DC power modules to provide up to 25A of output current. Designed by sister company TDK Innoveta Inc, the new DOSA (Distributed Power Open Standard Alliance) standard footprint DC/DC converters provide exceptional thermal performance and are designed for engineers seeking to save space and system cost in 48V distributed power architectures.

The iSA series sixteenth-brick converter family uses a stacked two-board construction that offers superior thermal performance and cooler operation due to the heat-dissipating components being on the upper board and thus raised into the ambient air flow. This construction also minimises any airflow 'shadowing' effects, resulting in a thermal performance that exceeds that of larger footprint eighth-brick devices.

Furthermore, the sixteenth-brick power module has a 44 per cent smaller footprint than eighth-brick converters, freeing up valuable 'real estate' on circuit boards, and the low component count provides greater reliability and is said to make the module more cost-effective than others on the market. As well as being significantly smaller than eighth-brick power modules, the iSA Series DC/DC power module is claimed to be the highest power-rated sixteenth-brick currently available. It offers a wide input range (36-75V), and a broad range of outputs: 12V/6.5A (78W), 5V/15A (75W), 3.3V/25A (82.5W). These new low-voltage power modules are excellent for powering a broad range of systems including DPA, POLs, FPGA, ASIC, DSP, microprocessors, access, optical and industrial loads.

Standard features include remote sense, remote on/off, and auto-recovery functions to fully protect against input under-voltage, output over-voltage, output over-current and over-temperature protection. Latching output over-voltage is also offered as an option. Safety approvals include UL60950 (US and Canada), VDE 0805, CB scheme (IEC 950), and CE mark (EN 60950). The entire iSA series sixteenth-brick line is RoHS-compliant.
