iQE, iQG, iQL DC-DC Converters

TDK-Lambda DC-DC Converters are available in three models, IQG, IQL, and IQE DC/DC, all with standard quarter brick footprints. iQE Series is a 96W to 204W DC-DC converter with 18V_DC to 36V_DC and 36V_DC to 75V_DC nominal inputs and 3.3V/40A to 15V/10A nominal outputs. iQG Series, 300W to 396W converters with 36V_DC to 75V_DC input features 12V/25A or 33A outputs, a low 13.2 profile, and up to 95% operating efficiency. iQL Series is a 72W to 308W converter with 18V_DC to 36V_DC and 36V_DC to 75V_DC inputs and 2.5V/60A, 28V/11A nominal outputs. .
