Product information

Description

The MEAN WELL SKMW20G-03 is a compact DC-DC converter in a DIP through-hole package designed for PCB mounting. It accepts a wide input range of 18–75 VDC and provides a single regulated 3.3 VDC output capable of delivering up to 4.5 A. The module measures approximately 1" x 1" and features a remote ON/OFF function. Weighing 18 g and RoHS-compliant, this 20 W converter is intended for use where a small, reliable power source is required on a circuit board.

Advantages

The SKMW20G-03 offers a wide input voltage range (18–75 VDC) and consistent 3.3 V output at up to 4.5 A within a 1" x 1" ultra-compact footprint, enabling space-saving PCB designs. Its DIP through-hole package simplifies mechanical mounting and soldering on PCBs, while the remote ON/OFF feature allows external control of the converter. The unit is lightweight (18 g) and RoHS-compliant.

Suitable for

  • Embedded systems and single-board computers requiring 3.3 V supply
  • Industrial control and automation equipment with wide input rails
  • Telecom and networking devices powered from higher-voltage buses
  • Prototyping and PCB-mounted power solutions in compact devices

How to use

Mount the SKMW20G-03 on a PCB using the DIP through-hole pins and solder according to the board layout. Apply an input voltage within the specified 18–75 VDC range to the input terminals, and connect the load to the 3.3 V output with appropriate decoupling and wiring for up to 4.5 A. Use the remote ON/OFF pin to enable or disable the output from external control logic as required. Observe standard PCB layout practices for DC-DC converters, including grounding, input/output filtering, and thermal considerations.

Usage recommendations

Provide adequate board-level decoupling and keep high-current traces short. Ensure the input voltage stays within the specified range and derate the unit as needed near maximum output current or elevated ambient temperatures to maintain reliability.
