The iEH series of 300W 1/8th brick DC/DC converters from TDK-Lambda are said to use digital non linear adaptive control to improve dynamic response, system stability and reliability. This, says the company, makes the devices suitable for demanding applications, including communications and test and broadcast.
Devices in the iEH series can provide outputs of 9.6, 10.2, 10.8 or 12V DC from a nominal input of 48V DC.Digital control also enables component optimisation and an efficiency of up to 95.5%, allowing the unit to deliver 265W at 55°C ambient or 284W when fitted with an optional baseplate, both with an airflow of 1m/s. The converters can also be paralleled for by specifying the droop mode current share option.
Standard features of the iEH series include remote on/off, output over current protection, input under/over voltage protection, output over voltage protection and over temperature protection.
Devices have an input to output isolation of 2250V DC and an input to baseplate isolation of 1500V DC.
