Sixteenth bricks optimise thermal performance

Sixteenth brick DC/DC power modules now provide up to 25A of output current.

Lambda UK has strengthened its iSA series of sixteenth brick DC/DC power modules to provide up to 25A of output current.

Designed by sister company TDK Innoveta, the new DOSA (Distributed Power Open Standard Alliance) standard footprint DC/DC convertors 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 convertor family uses a stacked two-board construction claimed to offer superior thermal performance as the heat dissipating components are 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.

The sixteenth brick power module has a 44% smaller footprint than eighth brick convertors, freeing up valuable real estate on circuit boards, and the low component count provides greater reliability and a more cost-effective solution than other modules on the market.

As well as being significantly smaller than eighth brick power modules the iSA Series DC/DC power module is 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) and 3.3V/25A (82.5W).

The addition of these new low voltage power modules provides an ideal solution 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 undervoltage, output overvoltage, output overcurrent and overtemperature.

Latching output over voltage is also offered as an option.

Safety approvals include UL60950 (US and Canada), VDE 0805, CB scheme (IEC950), and CE Mark (EN60950).

The entire iSA Series sixteenth brick line is RoHS compliant.
