Flex Power Modules has added PKB5213D, new DC-DC converters to its PKB-D series of isolated eighth-brick DC-DC converters. The PKB5213D is a high-density DC-DC converter suitable for harsh environments. The power module works with a wide input voltage from 18-60V and provides a fully regulated 12 V output rated delivering power up to 240 W. The PKB5213D has high efficiency and can work at high temperatures. Furthermore, the isolated converter module saves the output loads from any fault occurring at the input side making it suitable for sensitive appliances and use in automotive, medical, and industrial applications.

An isolated DC-DC converter is a type of power converter that provides electrical isolation between the input and output circuits. This means there is no direct electrical connection between the input and output sides of the converter. Instead, the input and output are coupled through a transformer or other isolation mechanism, allowing the converter to step up or down the input voltage while providing electrical isolation.

The PKB5213D is a thermally optimised power module providing an uninterrupted 12V output rated at 20 A/240 W. This makes it suitable for use with sensitive and expensive equipment. The part’s Isolation of the module is 2250 VDC input to output and is safety-rated according to IEC/EN/UL 62368-1. The DC-DC converter offers up to 94.6% efficiency at 24 V input and 50% load. Since the module is suitable for sensitive applications, it comes with multiple safety features including input under-voltage lockout, output over-voltage, short circuit and current limit, and over-temperature protection.

David Xie, Director R&D and Product Management Shanghai of Flex Power Modules comments: “The PKB5213D our series of eighth brick DC/DCs with its wider input range down to 18 V, is now covering an even wider variety of applications”.
