## Summary description

MEAN WELL SKMW30G-03 is a 30 W power adapter/inverter with a wide input range of 18–75 V designed for converting supply voltages in industrial and vehicular applications. The unit complies with RoHS and is lightweight (18 g), suitable for compact installations, mass production or OEM use where reliable low-power conversion is required.

## Long description

MEAN WELL SKMW30G-03 is a compact DC-DC converter designed to deliver a regulated 3.3 V output at up to 7.5 A from a wide input range of 18–75 V DC. The module is supplied in a 1" x 1" DIP through-hole package intended for PCB-mounting and integrates a remote ON/OFF control for system-level power management. With a 30 W power rating, RoHS compliance and an 18 g lightweight construction, this converter is suitable for space-constrained industrial and vehicular electronics requiring reliable low-power conversion.
Advantages
The converter provides a stable 3.3 V single output with sufficient current for many embedded systems while accepting a wide input voltage, reducing the need for additional upstream regulation. Its ultra-compact 1" x 1" footprint and through-hole DIP form factor simplify PCB layout and mechanical mounting in production and OEM assemblies. The remote ON/OFF feature facilitates integration into systems that require external power sequencing or standby control. RoHS compliance and low weight make it appropriate for mass-produced and environmentally regulated products.
Suitable for
Embedded controllers and microprocessor boards requiring 3.3 V supply
Vehicle and transportation electronics operating from wide DC battery voltages
Industrial control modules with space-constrained PCB designs
OEM devices and mass-production assemblies where compact, PCB-mounted converters are needed
Key specifications
Function: DC-DC converter (step-down type)
Input voltage range: 18–75 V DC
Output voltage: 3.3 V DC
Maximum output current: 7.5 A
Output power: 30 W
Mounting: through-hole DIP for PCB installation
Package dimensions: approximately 1" x 1" footprint
Control: remote ON/OFF
Compliance: RoHS
Weight: ~18 g
How to use
Mount the module on the target PCB using the through-hole pins and ensure correct polarity and secure solder joints. Connect a suitable input voltage within the 18–75 V DC range and verify the input polarity before power-up. Use the remote ON/OFF pin according to the manufacturer’s logic-level specifications to control the converter output; if remote control is not required, follow the recommended default state as specified in the datasheet. Provide adequate PCB copper area and thermal vias if necessary to assist heat dissipation under continuous high-load conditions. Add input and output filtering or bulk capacitance per system requirements to minimise noise and ensure stable operation.
Usage recommendations
For reliable long-term performance, operate the converter within its rated input and output limits, allow for derating at elevated ambient temperatures, and follow PCB layout guidance for grounding and thermal management as provided in the technical documentation.
