Small Technology Research Group (STRG, Taiwan) announced its new ESC Series of 12W to 35W, dc/dc power converters. The new ESC modules are believed to one of the first power modules with a built-in input, EMC filter to meet the conducted EMI limits of EN55022 Class B or FCC Part 15J, Level B, without added external components. The modules offer a low-EMI replacement for the popular 2in x 2in standard packages in 60% of the size with higher efficiency and the same pinout.
The modules not only save the 40% footprint but also save the spaces of the external EMI filter network. The modules can be used in distributed power or intermediate bus architectures in data processing, wireless, enterprise, access or optical networking equipment. The ESC modules deliver up to 10A, converting 18V to 36V or 36V to 75V input to a precisely regulated, single output from 15V to 1.5V. The modules achieve full-load efficiency of 89% at 3.3V output voltage.
The ESC converters offer a small size and low profile, measuring just 1.2in x 2.0in x 0.35in (30.48mm x 50.8mm x 8.9mm). A low-radiated EMI, six-sided, metal shielding construction offers exceptional thermal performance, capitalizing on a small footprint with the ability to operate in tightly packed card environments. The through-hole package has a pinout that is compatible with the popular industry-standard. All ESC Series modules offer output-current limiting and protection against output over-voltage, short-circuit, input under-voltage and over-temperature. The modules are capable of operating in case temperatures ranging from -40°C to +100°C.
The ESC Series converters are priced at $38 in 10,000-unit quantities. Samples are available now.
