The NGA series is a range of low profile DC/DC  
converters offering a single regulated output over  
a wide input voltage range. All parts deliver the full  
output power up to 85ºC without the need for exter-  
nal heatsinking while the synchronus rectification  
design yields excellent efficiencies up to 95%.

1.If optional VADJ and SD pin are required (as indicated in the mechanical dimensions diagram) include an E in the part number when  
ordering, i.e. NGA10S1505SEC & NGA10S1505DEC.  
2. Supply voltage should exceed output voltage by 1.45V.
