Notes
32. Clock Fail detector available for PWM_en bit is set to logic [1] and CLOCK_sel is set to logic [0].
33. The PWM ratio is measured at V
HS
= 50% of V
PWR
and for the default SR value. It is possible to put the device fully-on (PWM duty cycle
100%) and fully-off (duty cycle 0%). For values outside this range, a calibration is needed between the PWM duty cycle programming
and the PWM on the output with R
L
