Digital Control
Due to the EN pin, a digitally controlled luminosity can
be implemented by providing a PWM signal to this pin (see
Cycle, but care must be observed as the DC/DC converter
is continuously pulsed ON/OFF and noise are likely to be
generated.

NOTE: Pulse width and frequency depends upon the application constraints.
Figure 31. Typical Semi?Pulsed Mode of Operation
The PWM operation, using the EN pin as a digital
control, is depicted in Figures 32 and 33. The tests have
been carried out at room temperature with V bat = 3.60 V,
L = 22 m H, five LEDs in series, RFB = 22 W .
