2.2.10 Combination Linear and PWM Dimming
A combination of linear and PWM dimming techniques
can be used to achieve a large dimming ratio.
Note: The output current will not go to zero if the LD
pin is pulled to GND because the minimum gate driver
on-time is equal to the current sense blanking interval.
To achieve zero LED current, the PWMD pin should be
used.
