300W 1/8th Brick DC-DC Converter has Digital Control
TDK Corporation has announced the introduction of the 300W TDK-Lambda iEH series of isolated dc-dc converters. Featuring digital non-linear adaptive control, these converters provide better dynamic performance, improved system stability and reduced component count. The iEH48033A096V provides 317W with a nominal output voltage of 9.6 Vdc from an input voltage range of 45- to 55-Vdc with an efficiency of 94% (measured at 48-Vdc input). The iEH48025A120V provides 300W with a nominal output voltage of 12Vdc from an input voltage range of 36- to 75-Vdc with an efficiency of 94.6% (also measured at 48-Vdc input).
The series is designed to meet a wide range of applications, including Information and Communication Technology (ICT) equipment, semiconductor manufacturing equipment, measuring equipment and general industrial equipment. The converters are in the industry standard eight-brick package (58.4 x 22.9 x 13.5mm) and include a baseplate with mounting holes for use with an external heatsink. Optimization of components using digital control enables up to 192W of output power with only 200LFM airflow in an 85 degrees C ambient.
Input to output isolation is 2,250Vdc and input to baseplate is 1,500Vdc. All models feature remote on/off, over current, input under/over voltage protection, output over voltage protection and over temperature protection. The operating temperature range is -40 to +85 degrees C.
