SETTING FULL SCALE LED CURRENT
The maximum or full scale LED current is set either using an external set Resistor ( RISET) and CURRENT and
CURRENT_MAX EPROM bits or just using the CURRENT and CURRENT_MAX EPROM bits. Table 3
summarizes setting of the full scale LED current.

SETTING PWM DIMMING FREQUENCY
LP8556 PWM dimming frequency can be set either by an external resistor, RFSET, or by pre-configuring EPROM
Memory (CFG5 register, PWM_FREQ[3:0] bits). Table 4 summarizes setting of the PWM dimming frequency.
Note that the RFSET is shared for setting the boost switching frequency, too. Setting the boost switching
frequency and PWM dimming frequency using an external resistor is shown in Table 5.
