Output current detection reference
Connect the ground terminal of the external resistor RF to
this pin.
Output current detection
Connect a resistor with a small value between this pin and
RFGND.
This sets the maximum output current I
Outputs (External transistor drive outputs)
These are the PWM outputs used for duty control.
These are push-pull outputs.
