PART NUMBER: VHB75W  
DESCRIPTION: half-brick dc-dc converter  
description  
The VHB75W series of DC-DC converters  
are designed for high reliability  
features  
·37.5-75W isolated output  
·Efficiency to 85%  
applications, featuring over-temperature  
protection, over-current protection. The  
wide 4:1 input range (9-36V or 18-75V) is  
very useful to stabilize an input source  
like batteries in various discharging and  
charging conditions. Additionally, high  
efficiency, fast response, tight  
·300 kHz switching frequency  
·regulated output  
·continuous short circuit  
protection  
·industry standard half-brick size  
·remote on/off  
·over-temperature protection  
·over-current protection  
regulations, remote sense and remote  
On/Off control make these converters  
very useful in many applications.
