Tunable-Loop Low-Profile Non-Isolated DC-DC Converters

Bel Power Solutions, a Bel group company has announced the new SLDM Tunable Loop™ SLDM-06D1Ax and SLDM-12D1Ax modules, which are ultra-low profile, non-isolated dc-dc converters that deliver up to 6A and 12A with maximum flexibility of being mounted on the top side or bottom side of the host PCB.

The SLDM modules fit into the smallest, tightest spaces (only 2.8mm high, less than the combined height of 2 pennies!). They can be mounted in areas on the top side where ultra-low profile is required either due to airflow impeding issues or mechanical interference issues, or they can be mounted on the PCB bottom side to save top side real estate.

Both modules can be used on bottom side reflow applications, underneath boards, mezzanine and in very dense power applications. The PMBus on board allows power system architects to control the power train using a 3-wire interface (data, clock and GND).

Other features include a Power Good signal, fixed switching frequency, output overcurrent protection (non-latching), over-temperature protection, a remote on/off and ability to sink and source current.

Operating over a wide input voltage range of 3Vdc to 14.4Vdc, SLDM modules provide a precisely-regulated output voltage from 0.45Vdc to 5.5Vdc. Programmable via an external resistor, they have a DOSA-standard footprint and are pin-to-pin with the GE SlimLynx™ Series.

Typical applications include distributed power architectures, intermediate bus voltage applications, telecommunications equipment, server/storage/networking applications and industrial equipment.

The SLDM Tunable Loop™ product will be in stock with Mouser and Digi-Key beginning 2018.
