MagI³C Power Module
VDRM - Variable Step Down Regulator Module
It is also possible to synchronize the switching frequency to an external clock signal. See the Step 8.Synchronization CLK
option section for further details. While it is possible to set the operating frequency higher than 400 kHz when using the
device at output voltages of 5 V or less, minimum duty cycle and pulse skipping issues restrict the maximum recommended
input voltage under these conditions. The recommended operating conditions for the MagI³C Power Module can be
summarized by Figure 1. The graph shows the maximum input voltage vs. output voltage restriction for several operating
frequencies. The lower boundary of the graph shows the minimum input voltage as a function of the output voltage.
