Functional Description and Electrical Characteristics
Note: The Duty Cycle of 100% can be achieved. Although the above formula may result in duty cycle values
greater than 100%, the actual duty cycle is of course limited to 100%.
Equation: PWM duty cycle readout for constant current mode operation
(12)
Equation: PWM duty cycle readout for direct PWM mode operation
Note: The Duty Cycle of 100% can be achieved. Although the above formula may result in duty cycle values
greater than 100%, the actual duty cycle is of course limited to 100%.

DATA
PWM duty cycle
This will report the duty cycle bits in the register. If the channel is set
to “Current Control” the feedback will represent the value calculated
by the PI controller. If the channel is set to “direct PWM” the feedback
will represent the value in the register programmed by a SPI write with
bits 11 and 12 always read as 0. See the “Control Method and Fault
Mask Configuration” message.
