How SMD DC-DC Converters Enhance PCB Design and Assembly

Surface mount technology has become an attractive method for mounting components to printed circuit boards (PCBs) – and for good reason. Attaching components to boards via solder paste instead of larger pins saves board space and assembly time. Designers tasked with space constraints demand smaller components, increasingly looking for surface mountable (SMD) power components like DC-DC converters to satisfy this critical requirement. Surface mount technology and SMD components provide the following benefits:

  • Higher component density allows for smaller circuits and faster circuit speeds.MTWA4-5S5-SM 1
  • Faster, more efficient assembly with greater control.
  • Both sides of the PCB can be used.
  • Fewer holes need to be drilled into the PCB.
  • Less noise thanks to lower radiated emissions.
  • Lower mass of components bolsters shock and vibration resistance.
  • Customization: A variety of components can be attached to the PCB.

A Diverse, Growing Lineup of SMD DC-DC Converters

Polytron Devices offers a wide range of SMD-packaged DC-DC converters rated at 2, 3, 3.5, 5 and 8 watts of output power with single and dual outputs. The lineup of DC-DC converters includes models with regulated or unregulated outputs and isolation between input and output from 500V DC to 1,600V DC plus models with 2MOPP 5,000V DC isolation for medical applications.

Offering wide 4:1 and 2:1 input voltage ranges, the converters are suitable for applications with inputs ranging from 5 VDC to 110 VDC. Single-output voltages range from 3.3V to 24V DC and dual-output voltages range from ±5 to ±15V DC. Additional features include high efficiency, wide temperature ranges, short circuit and overvoltage protection, small footprints and five and six-sided EMI shielding. Polytron SMD DC-DC converters have the model numbers: TWA3TWA5TWB5TWA8TWB8 and TWB12. In addition, certain SMD DC-DC converter models are particularly appropriate for use in specialty applications such as MTWA2 and MTWA4 for medical and TWB8 for railroad equipment.
