The QAS family of DC to DC converters were designed to provide higher output voltages
for special telecom and industrial applications. The QAS features remote sense pins for
accurate point of load regulation, has a 5 sided shield, and has 1500VDC of isolation.
The QAS also output voltage trim, over current, short circuit, and over voltage protection
allowing use in a wide range of applications.
