operating from a 38 to 53 Vdc primary bus to deliver an  
isolated 19.0 V to 26.5 V secondary. The bus converter  
may be used to power non-isolated POL converters or as  
an independent 19.0 – 26.5 V source. Due to the fast  
response time and low noise of the bus converter, the  
need for limited life aluminum electrolytic or tantalum  
capacitors at the load is reduced—or eliminated—  
resulting in savings of board area, materials and total  
system cost.

efficiency and safe operating temperature range, the bus  
converter does not require a discrete heat sink in typical  
applications. Low junction-to-case and junction-to-lead  
thermal impedances assure low junction temperatures  
and long life in the harshest environments.
