Note:
5)
6)
This is the minimum PWM frequency to maintain a continuous output. Lower frequencies can be used, but will result in gated operation of
the device i.e. device enters shutdown when EN is low (see Note 6).
This is the time for which the device remains active after the EN pin has been driven low. This delay allows a continuous output to be
maintained during PWM mode operation at frequencies higher than 10kHz.
