TDK-Lambda’s i7C 300W high-density buck-boost non-isolated dc-dc converters are suitable for producing additional dc output voltage rails up to 300W from a single output 12V, 24V, or 48V ac-dc power supply. Units accept a wide dc input voltage range with a wide output adjustment range. Featuring a Power Good signal with options for switching frequency synchronization as well as output current monitoring.  Units are available in three mechanical configurations – low profile open frame, baseplate construction for conduction cooling, and integrated heat sink for convection and forced air cooling. With up to 300W in a 1/16 brick pin-out, the converters offer high power density with less board space, and feature up to 97% efficiency, allowing for longer battery life and lower power consumption.
