TDK Extends Sixteenth Brick Line

May 10, 2007 by Jeff Shepard

TDK Innoveta Inc. has strengthened the recent iSA series of 1/16 Brick dc-dc power modules by adding to the range of low output voltage products offered. The new 3.3V/25A (82.5W), 5V/15A (75W) and 12V/6.5A (78W) devices are said to provide exceptional thermal performance using the industry standard DOSA 1/16 brick footprint which is 44% smaller than eighth bricks. Providing higher power ratings, these dc-dc converters are said to be well-suited for engineers seeking to save space, improve thermal performance and reduce system cost in 48V power architectures for telecom, datacom, access, wireless and many other applications.

The unique stacked 2 board construction of the iSA Series Sixteenth brick converter family offers superior thermal performance and cooler operation due to the heat dissipating components being on the upper most board, and this being raised into such ambient air flow as is present. This construction also minimizes any airflow ‘shadowing’ effects, resulting in a thermal performance that exceeds that of larger footprint eighth brick devices.

Using circuitry from the TDK Innoveta iEA range of eighth brick converters, the low component count on the iSA dc-dc converters is said to provide greater reliability and a more cost effective solution than other modules on the market. The TDK Innoveta iSA Series of dc-dc power modules features what is claimed to be the highest power rating of sixteenth brick products currently available. It boasts a wide input range (36-75V), and a with the addition of these three new low voltage power modules provides the ideal solution for powering a broad range of systems including DPA, POLs, FPGA, ASIC, DSP, microprocessors, access, optical and industrial loads.

The input is fully isolated from the output further adding to the versatility by allowing different polarity and grounding connectivity. Standard features include fixed frequency operation, remote sense, remote on/off, and auto-recovery of input under voltage, output over voltage, output over current and over temperature protection circuitry. Latching output over voltage protection and positive polarity on/off are offered as options. TDK Innoveta’s entire iSA Series Sixteenth brick line is RoHS compliant.

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