Power adapter/inverter MEAN WELL DPB09A-15, 9 W, 15 V, 0.3 A

MEAN WELL DPB09A-15 is a compact DC-DC regulated converter in a SIP through-hole package. It accepts a wide input range and provides dual isolated outputs of ±15 V with up to ±0.3 A per rail. The module is intended for PCB mounting and embedded low-power DC applications and is RoHS compliant. Its small size and 24 mm depth make it suitable for volume production and space-constrained designs.

Advantages

The DPB09A-15 offers regulated dual outputs with isolation between rails, a wide 9–18 V input range, and remote ON/OFF control for system-level power management. Its SIP through-hole package simplifies PCB assembly and mechanical retention, and the low profile and 5 g weight support compact, lightweight designs. Supplied in large packs, it is suitable for automated assembly and high-volume manufacturing.

Suitable for

• Embedded electronics and control boards
• Signal conditioning and analog circuits requiring ±15 V rails
• Test equipment and instrumentation with low power needs
• Volume production and automated PCB assembly

How to use

Mount the DPB09A-15 into the corresponding PCB footprint and solder the through-hole pins according to the board layout. Apply a DC input within the 9–18 V range to the input pins and observe polarity. Use the remote ON/OFF pin per the manufacturer's recommended logic levels to enable or disable the outputs. Verify that the combined load on both rails does not exceed the rated ±0.3 A per rail and follow thermal management practices for continuous operation.

Recommendations

For reliable operation, ensure input voltage is well-regulated and within the specified range, add input filtering if the source is noisy, and provide adequate PCB copper area for heat dissipation. Consult MEAN WELL application notes for recommended decoupling and layout to minimize noise and maintain output regulation.
