DC-DC Converter Circuit
When an open detection circuit is available, Osc_D pin is set to open, the IC shuts down. If the pin is shorted to
GND at startup, the IC fails to start operating. (It does not detect in a default.) In the DC-DC converter
operating mode, channel B starts operating before channel A or C.
