Operating from 48 Vdc nominal input, 504 W models of TDK-Lambda iQG series offer 12 V, 42 A outputs and up to 96.3% efficiency. Dual cooling technique enables delivery of 38.5 A (438 W) in 55°C ambient with airflow of 400 LFM. With 0.5 in. heat sink and 400 LFM airflow, delivery of 504 W at 70°C is possible. Accepting 39–75 Vdc input, products maintain tight output tolerance of ±210 mV (±1.7%) for all input, loading, and temperature variations. Droop mode current share option is available.
