TDK Corporation is introducing the iEH series of 300W 1/8th brick DC-DC converters. Utilising digital non-linear adaptive control, these converters offer improved dynamic response, better system stability and increased reliability due to a reduced component count. This makes the series well suited for demanding communications, test and broadcast applications.
TDK’s iEH series can provide output voltages of 9.6, 10.2, 10.8 or 12V DC with currents up to 33A from a nominal input of 48V DC. The digital control also enables component optimisation and high efficiency up to 95.5 per cent to deliver 265W of output power at 55degC ambient, or 284W with the optional baseplate, with just 1m/s airflow. In addition, the converters can be paralleled for additional power by specifying the droop mode current share option.
The converters are in the industry standard eighth brick package measuring 58.4 × 22.9 × 12.7mm. 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.
All iEH models are fully isolated with an input to output isolation of 2250V DC and 1500V DC input to baseplate. Safety certification includes IEC/EN 60950-1, UL 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
