Hardware Operation
This section includes the general guidelines for operating the EVK. To configure the EVK and achieve optimal
performance, follow these steps:
Before you power-up the EVK, set the H1 and H2 PCB headers by fitting the jumper sockets. In Figure 6, H1
1.
is in the enable position and H2 is in fixed-frequency mode.
H3 sets the EVK division ratio. In Figure 6, H3 is set to divide-by-2 mode, and all the other extra functions
2.
are NOT implemented. If the H3 header is left unused, the EVK powers up in divide-by-3 mode by default.
Do not leave H3 without a jumper in the HIGH or LOW position.
Verify that all power and sensing connections are made correctly. Minimize the wire lengths.
3.
Apply the input voltage.
4.
After the EVK starts up successfully, apply the load current.
