Dc-dc converter modules offer very high power density

RECOM RPX modulesā€™ outstanding thermal performance and innovative 3D Power Package technology enable fanless operation at high ambient temperatures while supplying output currents up to 4.0 A.

The RPX series of dc-dc converter modules from RECOM are complete power modules with integrated power transistors and inductors, requiring only input and output capacitors and voltage-setting resistors to form fully functioning power regulators with various maximum current ratings up to 4 A. The RPX modulesā€™ wide input-voltage ranges mean that they can be used in circuits with a supply voltage of 5 V, 12 V, 15 V or 24 V dc.Ā 

The RPX-1.0, RPX-1.5, RPX-2.5 and RPX-4.0 power modules are supplied in thermally-enhanced, surface-mount QFN packages that have a small footprint and offer high power density. The 3D power packaging design developed by RECOM features an integrated inductor and a control IC embedded in the substrate, reducing the system footprint. The excellent thermal performance of the RPX modules means that they can operate at temperatures up to at least 85Ā°C without forced-air cooling.Ā 

Built-in protection functions include short-circuit protection, over-current limiting and thermal shutdown. A resistor divider on the input allows an under-voltage lockout voltage to be set to protect battery-powered supplies from over-discharge. A resistor divider on the output controls the setting of the output voltage over a very wide range, while an enable input provides for voltage supply sequencing.

Some products in the RPX series are now also offered as -Q variants, qualified to AECā€‘Q100 Grade 1 for operation up to 125Ā°C. These modules include wettable flanks, which facilitate automated optical inspection of the land-grid array solder joints.

All modules are readily available on short lead times from Future Electronics.
