Power adapter MEAN WELL DKMW20F-15 20 W 15 V 0.66 A

The MEAN WELL DKMW20F-15 is a compact DC-DC converter designed for PCB mounting. It accepts a wide input range of 9–36 VDC and provides dual bipolar outputs of ±15 V with a maximum output current of ±0.66 A per rail. The module comes in a DIP through-hole package with an ultra-compact 1" x 1" footprint and includes a remote ON/OFF control. The converter is RoHS compliant and weighs approximately 18 g, making it suitable for size- and weight-sensitive electronic designs.

Advantages

The DKMW20F-15 offers a small board-mounted form factor that simplifies integration into existing PCB layouts while providing dual isolated outputs for bipolar supply needs. Its wide 9–36 V input range allows use with a variety of battery and intermediate bus voltages. The remote ON/OFF feature enables system-level power control, and the lightweight construction reduces mechanical load on the host board.

Suitable for

• PCB-mounted power supply for analog and mixed-signal circuits
• Industrial control modules requiring bipolar rails
• Battery-powered systems and vehicle electronics with 9–36 V sources
• Compact embedded systems and instrumentation

How to use

Mount the DKMW20F-15 into the PCB using the DIP through-hole pins and ensure correct orientation and soldering for reliable electrical and mechanical connection. Connect a 9–36 V DC source to the input pins, observe proper polarity, and route the ±15 V outputs to the target circuit loads within the specified current limits. Use the remote ON/OFF pin according to the manufacturer’s logic level requirements to enable or disable the outputs as part of system power sequencing.

Recommendations

For stable operation, provide adequate input decoupling and ensure the board area around the converter allows for airflow. Verify that the combined load on each output does not exceed ±0.66 A, and follow MEAN WELL's application notes for thermal considerations and recommended PCB layout to maintain reliability.
