PWM OPERATION
The built−in PWM are fully independent and can be
programmed to any value during the normal operation of the
NCP5623B chip. The PWM operate with five bits, yielding
a 32 steps range to cover the full modulation (0 to 100%) of
the associated LED:
PWM = $00 ³ the associated LED is fully OFF,
whatever be the programmed ILED value
PWM > $00 but < $1F ³ the brightness of the
associated LED is set depending upon the PWM
modulation value
PWM = $1F ³ the associated LED is fully ON, the
current being the one defined by the ILED value.
Each PWM is programmable, via the I
2
C port as depicted,
at any time under any sequence arrangement as requested by
the end system’s designer. The PWM does not change the
ILED value, but merely modulate the ON/OFF ratio of the
associated LED. What’s more, none of PWM is changed by
NCP5623B during gradual dimming.
