DC/DC converters have built-in filter to simplify power design
5 July 2017 
The converters range from 3.0 to 6.0W and have a built-in EMI filter to save components and board space. This means that the converters require no external filter components to pass EN 55022 class-A EMI tests. They will also pass the class-B tests for domestic products, with only a small capacitor added.
The 3.0, 5.0 and 6.0W converters can drive high capacitive loads, and provide a regulated 5.0V output working from a nominal 5.0 or 24V DC input. They are robust, with continuous short-circuit protection, over-load protection and optional under-voltage lockout, and are specified for operation from -40 to +68°C without derating, or 100°C with derating. They are suitable for use in a variety of industrial electronic equipment.
The 31.8 x 20.3 x10.2mm DIP24 modules are easy to design and assemble, says the company. The converters operate at up to 81% efficiency to deliver reliability and energy savings. They are UL60950, UL62368, and IEC/EN62368-1 certified, and all units carry a three-year manufacturer’s warranty.
