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 VHS = 50% of VPWR 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 RL = 5.0  resistive load.

34.

Typical value guaranteed per design.

35.

Value guaranteed per statistical analysis.

otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions unless

otherwise noted.
