A power supply design based on LT3748

This paper describes in detail how to select components of the peripheral circuits of LT3748. In this paper, the LT3748 is introduced to produce an 8V
out
at 3A from the nominal input voltage −48V with an operating input voltage range of −38.4V to −72V, where −48V is a common telecommunications equipment voltage. The test results show the output voltage and the current meet the demand of the project and the efficiency of the circuit is about 70%.
