i6A Series 

250W, 9 to 40V Input Non-Isolated Step-Down DC-DC Buck Converter 

https://product.tdk.com/en/power/i6a www.emea.lambda.tdk.com/i6a 

The i6A series of non-isolated DC-DC step-down converters are ideal for creating additional high current output voltage rails from a single output 12V or 24V AC-DC or DC-DC power supply. The highly efficient i6A series accepts a wide DC input and has a wide output adjustment range in compact 1/16th brick package. Output trim, remote sense, negative or positive logic remote On-Off comes as standard features. Power good, frequency synchronization and output sequencing are optional features.
