## Long description

The MEAN WELL SKMW20F-03 is a compact DC-DC converter module in a 1" x 1" DIP through-hole package. It accepts a wide input voltage range of 9–36 Vdc and provides a regulated single output of 3.3 Vdc at up to 4.5 A, delivering 20 W of output power while meeting RoHS environmental requirements. The module includes a remote ON/OFF feature and is designed for PCB mounting in space-constrained applications.
Advantages
This converter combines a small footprint and light weight (approximately 18 g) with a wide input range and a stable 3.3 V output capable of 4.5 A continuous current. The through-hole DIP package simplifies PCB assembly and mechanical retention. RoHS certification ensures compliance with environmental regulations, and the remote ON/OFF control provides flexible power management for embedded systems.
Suitable for
 Embedded systems and single-board computers requiring 3.3 V regulation
 Industrial and telecommunications equipment with 9–36 V supply rails
 PCB-mounted power supplies in compact or space-limited designs
 Bulk installations and manufacturing runs (available in multi-piece packs)

How to use
Mount the SKMW20F-03 on the PCB using standard DIP through-hole soldering practices and ensure correct polarity for input and output connections. Provide adequate copper area or thermal paths on the PCB if required by your application to help dissipate heat at maximum load. Use the remote ON/OFF pin according to your system control logic to enable or disable the output as needed. Verify input voltage is within the 9–36 Vdc range before powering the module.
Usage recommendations
For reliable operation, allow sufficient airflow around the converter and avoid operation at maximum current in enclosed, poorly ventilated areas. When designing the PCB, follow MEAN WELL recommended layout practices for decoupling and thermal management and perform thermal testing at the intended ambient temperature and load conditions.
