NCP1607
Application Information
ON Semiconductor provides an electronic design tool, a
demonstration board and an application note to facilitate
the design of the NCP1607 and reduce development cycle
time. All the tools can be downloaded or ordered at
www.onsemi.com.
The electronic design tool allows the user to easily
determine most of the system parameters of a boost
pre−converter. The demonstration board is a boost
pre−converter that delivers 100 W at 400 V. The circuit
schematic is shown in Figure 41. The pre−converter design
is described in Application Note AND8353/D.
